2025 SEA Games
24ms
The 2025 SEA Games, officially the 33rd SEA Games and commonly known as Thailand 2025, is an international multi-sport event sanctioned by the Southeast Asian Games Federation. Get ready for the action from December 9th to 20th, 2025, across the vibrant Bangkok Metropolitan Region and the beautiful Chonburi province in Thailand. This marks the seventh time Thailand has hosted this prestigious event, with Bangkok having a rich history of hosting four times before.
The selection of host cities this year was groundbreaking, utilizing a new bidding and election process for the SEA Games. While the original co-host, Songkhla province, had to withdraw due to devastating floods, Bangkok and Chonburi are ready to welcome the world.
The journey to Thailand 2025 has been dynamic. In 2017, the Philippines initially withdrew its hosting duties for the 2019 Games, but later confirmed its commitment. Thailand stepped in as a potential replacement, but ultimately, the Philippines proceeded with hosting. By December 2021, Thailand was nominated for the 2025 Games, with Malaysia and Singapore confirmed for 2027 and 2029 respectively.
The bidding process for Thailand 2025 emphasized cost-effectiveness, with a focus on utilizing existing venues and limiting the number of host cities. This collaborative approach ensures a memorable and efficient Games.
The official handover ceremony, a tradition of the SEA Games, took place in Phnom Penh, Cambodia, during the closing ceremony of the 2023 Games. The SEAGF flag was passed to Thai officials, symbolizing the passing of the torch.
A vibrant kick-off ceremony was held in Bangkok in December 2024, setting the stage for the Games and highlighting the themes of "Green SEA Games" and "Sustainable Paralympics," aiming for net-zero emissions.
The 2025 SEA Games will utilize existing venues, many with a rich sporting history, across the Bangkok Metropolitan Region and Chonburi province. Some events will also take place in outlying venues like Chiang Mai and Ratchaburi.
The Games are governed by steering and organizing committees, with the Prime Minister of Thailand chairing the Steering Committee and the Minister of Tourism and Sports leading the Organizing Committee.
The estimated budget for the 2025 SEA Games and the 2025 ASEAN Para Games is 2.055 billion Thai Baht, with funding from government budgets, sponsorships, and various revenue streams.
The sports program has been a subject of discussion and evolution. Amendments to the SEAGF Charter and Rules aim to ensure a balanced and competitive program, with a minimum of 36 to 41 sports. This edition will feature a diverse range of sports, including traditional favorites and new additions like Teqball, with a significant number of sports also contested in the Olympic Games.
The opening ceremony is scheduled for December 9th, 2025, at Rajamangala Stadium, officially opened by His Majesty King Vajiralongkorn. The closing ceremony will be held on December 20th, 2025, also at Rajamangala Stadium, with the SEAGF flag being handed over to Malaysia, the host for the 2027 edition.
All eleven National Olympic Committee members of the Southeast Asian Games Federation are expected to participate, with Timor-Leste joining for the first time as a full ASEAN member state. Athlete eligibility rules, including gender verification and strict passport checks, are in place to ensure fair play.
The Games calendar will feature a variety of events, with blue boxes indicating competition days and yellow boxes marking medal-awarding finals.
The design competition for the emblem, motto, and mascot has resulted in unique and culturally rich representations of the Games. The emblem embodies "Play by the Rules," while the motto "Ever Forward" reflects a spirit of progress. The mascots, "The San," represent diversity and celebration.
Concerns and controversies have arisen, including organizational issues, ban and reinstatement of pétanque, basketball player eligibility, and flag and national anthem errors. Political and diplomatic issues have also emerged, notably concerning the participation of Cambodian athletes amidst a border crisis.
Despite these challenges, the 2025 SEA Games promise to be a spectacular display of athleticism, sportsmanship, and cultural exchange, showcasing the spirit of Southeast Asia.
The 2025 SEA Games (Thai: กีฬาซีเกมส์ 2025, RTGS: Kila Sikem 2025, pronounced [kīː.lāː sīː.kēːm sɔ̌ːŋ.pʰān.jîː.sìp̚.hâː]), officially called the 33rd SEA Games (Thai: กีฬาซีเกมส์ ครั้งที่ 33, RTGS: Kila Sikem Khrangthi 33, pronounced [kīː.lāː sīː.kēːm kʰráŋ.tîː sǎːm.sìp̚ sǎːm]) and commonly known as Thailand 2025, is an ongoing international multi-sport event sanctioned by the Southeast Asian Games Federation (SEAGF). The event is scheduled to take place from 9 to 20 December 2025 across the Bangkok Metropolitan Region, as well as Chonburi province in Thailand.
The joint bid from the three provinces was awarded the Games on 13 January 2023, after Thailand was confirmed as the host country by the Southeast Asian Games Federation (SEAGF). This marks the first time that host cities were selected through a new bidding and election process for the SEA Games.
The 2025 SEA Games marks the seventh time Thailand has hosted the event, with Bangkok having previously hosted 4 times (1959, 1967, 1975, and 1985) and will be one of the two host cities this time along Chonburi. The other two Thai cities who hosted the games are: Chiang Mai hosted the 1995 edition and Nakhon Ratchasima hosted the 2007 edition.
The original co-host Songkhla province was planned to host some events, until floods caused by Cyclone Senyar struck shortly prior to the Games, which resulted in all events that were to be held in Songkhla to be relocated to venues in Bangkok and Chonburi.
== Development and preparations ==
=== Host selection ===
As per the traditions of the SEA Games, hosting duties are rotated among the member countries of the SEA Games Federation (SEAGF). Each member country is assigned a specific year to host the event, but they have the option to withdraw or opt out of hosting in that particular edition.
==== 2019 disruption ====
On 21 July 2017, the Philippine Sports Commission (PSC) announced its decision to withdraw support for the country's hosting of the 2019 SEA Games. The government chose to reallocate funds originally intended for the event to support the rehabilitation of Marawi, which had been devastated by the Marawi crisis. Additionally, it was later reported that the Philippine Olympic Committee's (POC) insistence on handling all aspects of the hosting—including finances, security, and the organisation of the Games, similar to how it managed the 2005 SEA Games—contributed to the PSC's decision to withdraw its support.
On 10 August 2017, Charouck Arirachakaran, the Vice President and Secretary General of the National Olympic Committee of Thailand (NOCT), stated that Thai Prime Minister Prayut Chan-o-cha had agreed to a replacement plan for the 2019 SEA Games following the Philippines' withdrawal. The potential host provinces for the event were Chiang Mai, Chonburi, and Songkhla.
However, six days later, the Philippines, through Philippine Olympic Committee (POC) President Peping Cojuangco, confirmed that it would host the 2019 SEA Games. This decision came after Cojuangco wrote to Philippine President Rodrigo Duterte, appealing for reconsideration of the country's earlier withdrawal.
==== 2025 confirmation ====
In December 2021, Thailand was nominated as the host country for the 2025 SEA Games during the SEAGF Council and Executive Board Meetings held in Hanoi, Vietnam. Five months later, the SEAGF Council and executive board officially confirmed Thailand as the host for the 2025 Games, with Bangkok initially nominated as the host city. Additionally, Malaysia and Singapore were confirmed as the host countries for the 2027 and 2029 editions of the SEA Games, respectively.
After the confirmation, this marked the seventh time that Thailand had hosted the SEA Games. The capital city, Bangkok, hosted the inaugural SEAP Games in 1959, and subsequently in 1967, 1975, and 1985, after the event had become known as the SEA Games. However, the 1995 and 2007 editions were held in the Thai provinces of Chiang Mai and Nakhon Ratchasima, respectively.
==== Bidding and election ====
On October 11, 2022, Chaipak Siriwat, the Vice President of the National Olympic Committee of Thailand (NOCT), revealed the framework for the bidding process for the 2025 SEA Games. He emphasised that the host cities or provinces should aim to organise the Games at a budget-friendly cost and that there would be no requirement to build new venues. Unlike the 2019 and 2021 editions, where competition venues were spread across 23 and 12 cities respectively, the number of host cities for the 2025 Games would be limited to 3 or 4.
In October 2022, Prachum Boontiem, the Vice Governor of the Sports Authority of Thailand (SAT), nominated eight bidding parties from twelve cities or provinces interested in hosting the 2025 SEA Games. The city Bangkok as well as the provinces of Chiang Mai, Nakhon Ratchasima, and Songkhla submitted sole bids, while Bangkok, Chonburi, Songkhla, Krabi, Phuket, Trat, Amnat Charoen, Sisaket, Ubon Ratchathani, and Yasothon were proposed as potential bidding provinces.
Although the official bidding process began in October 2022, some regions had already revealed their bidding campaigns earlier: Ubon Ratchathani in April 2016, Chonburi in January 2019, and Krabi, Phuket, and Trang in February 2021.
On January 13, 2023, the Sports Authority of Thailand (SAT) selected three provinces—Bangkok Metropolitan Region, Chonburi province, and Songkhla province—to host the 33rd SEA Games, while Nakhon Ratchasima province was chosen to host the 13th ASEAN Para Games. This decision was approved by the Cabinet of Thailand in February 2023. These four cities were the first in SEA Games and ASEAN Para Games history to be chosen through a bidding process.
==== Host city contract ====
During the first SEAGF council meeting for the 2025 SEA Games in June 2024, the host city contract was signed by Chadchart Sittipunt, the Governor of Bangkok, Thawatchai Srithong, the Governor of Chonburi province, and Somnuek Promkhieo, the Governor of Songkhla province. The ceremony followed the model of the Olympic and Asian Games host city agreements, marking the first time a SEA Games host city contract has been signed.
=== Handover ceremony ===
As per tradition, the handover ceremony of the SEAGF flag and the artistic performance for the 2025 SEA Games took place during the closing ceremony of the 2023 SEA Games in Phnom Penh, Cambodia, on 17 May 2023 at the Morodok Techo National Stadium.
First, the SEAGF flag was passed from Vath Chamroeun, Secretary General of the Cambodia SEA Games Organizing Committee (CAMSOC), Thong Khon, President of the National Olympic Committee of Cambodia (NOCC), and Tea Banh, Chairman of CAMSOC, to Prawit Wongsuwan, President of the National Olympic Committee of Thailand (NOCT), and Gongsak Yodmani, Governor of the Sports Authority of Thailand (SAT). Other delegates at the handover ceremony included Chaiyapak Siriwat, Vice President of the NOCT; Cherdkiat Atthakor, Thai Ambassador to Cambodia; Chadchart Sittipunt, Governor of Bangkok; Niti Wiwatwanich, Deputy Governor of Chonburi province; Jesada Jitrat, Governor of Songkhla province; Natt Intracharoen, Vice Secretary General of the NOCT; and Prachum Boonthiam, Deputy Governor of SAT. This was followed by the raising of the Thai flag and the playing of its national anthem.
The artistic performance for this segment, titled Sawasdee SEA Games, meaning Hello SEA Games in Thai, was performed by Kid Buaksib, a contemporary Thai dancer and artist. They were a finalist in seasons 1 and 2 of Thailand's Got Talent.
=== Kick-off ceremony ===
The kick-off ceremony for the 2025 SEA Games and the 2025 ASEAN Para Games was held at the Hua Mak Sports Complex in Bangkok on December 7, 2024. The event was attended by Sorawong Thienthong, Chairman of the Organizing Committee and Minister of Tourism and Sports (MOTS), along with Gongsak Yodmani, Governor of the Sports Authority of Thailand (SAT), representatives from the National Olympic Committee of Thailand (NOCT), the Paralympic Committee of Thailand (PCT), and various national sports associations.
The event also featured renowned athletes, including Vareeraya Sukasem, an Olympic skateboarder, and Saysunee Jana, a five-time Paralympic gold medalist in wheelchair fencing. Additionally, several celebrities joined the occasion, such as Matthew Deane, Khemanit Jamikorn, James Fagerlund, and Nakorn Silachai.
Sorawong announced that the 2025 SEA Games and the 2025 ASEAN Para Games will be held under the themes of Green SEA Games and Sustainable Paralympics. The games aim to achieve net-zero emissions by promoting eco-friendly transportation, utilising sustainable products, and selecting venues that prioritise environmental protection. This environmentally friendly vision will also be implemented in the 2025 FIVB Women's Volleyball World Championship was held in August 2025.
=== Venues ===
The 2025 SEA Games will utilise existing venues across Bangkok Metropolitan Region and Chonburi province, including those used by the 1985 SEA Games, the 1998 Asian Games, and the 2007 Summer Universiade previously held in Bangkok Metropolitan Region.
Bangkok Metropolitan Region, which includes Bangkok and the neighbouring provinces of Nakhon Pathom, Nonthaburi, Pathum Thani, Samut Prakan, and Samut Sakhon, will host the majority of the 42 sports. Meanwhile, Chonburi will host 15 sports. Only two events—men's football and skeet shooting—will take place in outlying venues, with men's football preliminaries held in Chiang Mai and skeet shooting in Ratchaburi.

=== Coordination Committee of the SEAGF ===
During the second SEAGF council meeting for the 2025 SEA Games in October 2024, the Coordination Committee of the SEAGF has been appointed to monitor the progress of organising the 2025 SEA Games. The committee is composed of Chaipak Siriwat, the Vice President of the National Olympic Committee of Thailand (NOCT), along with the Presidents of the other four National Olympic Committees.
=== Steering and Organizing Committees for the Games ===
Similar to the 2007 SEA Games and the 2008 ASEAN Para Games in Nakhon Ratchasima, the committees for the competition are divided into two main bodies. The Steering Committee, chaired by the Prime Minister of Thailand, is responsible for setting policies, providing recommendations, and allocating budgets to the Organizing Committee. Meanwhile, the Olympic Organizing Committee, chaired by the Minister of Tourism and Sports (MOTS), is tasked with managing the operations of the competition, coordinating with various subcommittees, and overseeing the budget allocated by the Steering Committee.
In December 2024, the Steering Committee recognised the organisational structure of the Organizing Committee for the Games. Unlike the previous games, the chairpersons of the subcommittees are all from the Ministry of Tourism and Sports (MOTS) and the Sports Authority of Thailand (SAT), with no representatives from the National Olympic Committee of Thailand (NOCT).
=== Budget ===
The initial estimated budget for the 2025 SEA Games and the 2025 ASEAN Para Games is ฿2.055 billion. The funding for the events will come from several sources: ฿1.683 billion is being requested from the government budget. Additional revenue includes ฿20 million from sponsorships and ฿180 million from goods and services, such as sports equipment and beverages. Ticket sales are expected to generate ฿20 million. Registration fees for the SEA Games will contribute ฿134.40 million, while registration fees for the ASEAN Para Games will bring in ฿16.80 million.
The budget for these events is lower than the cost of the 1998 Asian Games, which was ฿2.372 billion, but higher than the 2007 Summer Universiade, which amounted to ฿1.843 billion. Meanwhile, the costs for the 2007 SEA Games and the 2008 ASEAN Para Games were ฿1.463 billion.
=== Torch relay ===
The torch relay of the games was begun on November 16 at Bangkok.

=== Opening ceremony ===
The opening ceremony of the 2025 SEA Games was held on 9 December 2025 at Rajamangala Stadium and opened by King Vajiralongkorn.

==== Charter and Rules amendment ====
Over the years, the SEA Games programme have faced criticism for being a "gold-medal mine" for host countries. Hosts have had the freedom to exclude Olympic and Asian Games sports that are disadvantageous to them while including non-Olympic sports or events that increase their medal chances. In some extreme cases, obscure sports have been selected to give the host country an advantage. This practice highlights the vulnerability of the Southeast Asian Games Federation (SEAGF) and its Charter and Rules, which grant excessive power to the host nations.
To avoid the bizarre situations seen in recent editions of the SEA Games, Thailand proposed a series of amendments to the SEAGF Charter and Rules in Section 34 during the 2013 edition. Although the Charter and Rules have been amended multiple times since then, host countries were still allowed to allocate their optional sports programs without oversight from the SEAGF. However, following the controversy surrounding the sports program in recent editions, the host countries for the three editions between 2025 and 2029—Thailand, Malaysia, and Singapore—agreed to propose further amendments to the Charter and Rules. The new amendments were unanimously approved by SEAGF members at the SEAGF Council meeting during the 2023 SEA Games. This upcoming edition will be the first to implement the new rules.
Section 34 of the amended SEAGF Charter and Rules stipulates that starting with the 2025 edition, the SEA Games program will include a minimum of 36 to 41 sports. This will consist of 12 compulsory sports under Category I, which are included in both the Olympic and Asian Games, a minimum of 25 Olympic and Asian Games sports under Category II, and a maximum of 4 additional sports under Category III. The medal events in Categories I and II must align with the Olympic and Asian Games programs, while events in Category III sports cannot exceed eight and must be selected from a pre-established list, which is determined a few years in advance.
==== Sports selection ====
Following the selection of the host cities, the Sports Authority of Thailand (SAT) initially announced that the 2025 SEA Games would feature forty-three sports, in accordance with the Games' charter. All of these sports are included in the Thailand National Games, and the host cities and provinces are equipped to provide the necessary venues and facilities to accommodate these events. Artistic swimming and equestrian will make their return, having last been included in 2017. Open water swimming, Muay Thai (muaythai), netball, and winter sports—including figure skating, ice hockey, and short track speed skating—will also return, having last been featured in 2019. Archery, rowing, and shooting will return as well, having last been included in 2021. Teqball will make its debut at the 2025 SEA Games.
During the first SEAGF council meeting for the 2025 SEA Games in June 2024, the organising committee proposed hosting forty sports, and the member countries agreed to finalise a second shortlist for the sports programme. Dancesport, ju-jitsu, karate, kurash, soft tennis, and weightlifting were removed from the second shortlist. Kabaddi and roller skiing were initially expected to debut but were also removed from the second shortlist. Polo (grouped with equestrian) and rugby sevens will make their return, having last been included in 2017. Baseball as well as softball, canoeing, and modern pentathlon will also return, having last been featured in 2019. Handball will return as well, having last been included in 2021. Additionally, 3x3 basketball (grouped with basketball), kickboxing, snooker (grouped with billiards), and triathlon have been reinstated, having last been part of previous games. Furthermore, figure skating and short-track speed skating have been combined into a single ice skating group.
After the 2021 Asian Indoor and Martial Arts Games in Bangkok and Chonburi were cancelled on 20 August 2024 due to the organisers' failure to meet obligations, local athletes affected by the cancellation were given the chance to compete in other international tournaments, including the 2025 SEA Games. In September 2024, the sports programme was confirmed to include nine additional sports: ju-jitsu, karate, weightlifting, and wushu, all of which will be reinstated. Other sports added include bowling, chess (including makruk), cricket, extreme sports, and squash. Extreme sports were group of sports climbing, skateboarding, waterskiing, and wakeboarding. Additionally, kabaddi and woodball were expected to make their debut at the event.
Furthermore, BMX, mountain bike racing, road racing, and track cycling were added to the cycling discipline, while aerobic gymnastics, artistic gymnastics, and rhythmic gymnastics was included in the gymnastics category. Kiteboarding and Windsurfing became part of the sailing discipline, and dragon boat was incorporated into the canoeing and rowing group. Futsal was added to the football category, and chinlone was introduced as a variant of sepak takraw. Beach volleyball was recognised as part of the volleyball discipline. Later, in October 2024, jet skiing was included in the extreme sports group.
Sports climbing and track cycling will make their return, having last been included in 2011 and 2017, respectively. BMX, rhythmic gymnastics, skateboarding, squash, waterskiing, and wakeboarding will also return, having last been featured in 2019. Bowling, chess, and futsal will make a comeback as well, with their last inclusion in 2021. Aerobic gymnastics, artistic gymnastics, beach volleyball, chinlone, cricket, dragon boat racing, jet skiing, mountain bike racing, road racing, and windsurfing have previously been part of past games. Kiteboarding and makruk will debut at these games.
During the second SEAGF council meeting for the 2025 SEA Games in October 2024, the organising committee finalised a sports programme featuring 569 medal events in fifty sports. Many traditional disciplines within these sports were included, such as the compound bow and recurve bow in archery; canoe sprint in canoeing; dressage, eventing, and show jumping in equestrian; épée, foil, and sabre in fencing; field hockey and indoor hockey in hockey; combat and kata in judo; ne-waza, fighting, and duo in ju-jitsu; kumite and kata in karate; ring and tatami in kickboxing; triathle and biathle in modern pentathlon; combat and waikru in muaythai; regu, quadrants, and hoop in sepak takraw; pistol, rifle, and shotgun in shooting; kyorugi and poomsae in taekwondo; duathlon and aquathlon in triathlon; freestyle wrestling and Greco-Roman wrestling in wrestling; and sanda as well as taolu in wushu.
Additionally, some disciplines were introduced for the first time, such as baseball5 in baseball, canoe slalom in canoeing, coastal rowing in rowing, hockey5s in hockey, and obstacle laser-run in modern pentathlon. Meanwhile, practical shooting made its return, having last been included in 2005. Furthermore, air sports (including paragliding and paramotor), flying disc (including disc golf and ultimate) and tug of war will be featured as demonstration sports.
During the third SEAGF council meeting for the 2025 SEA Games in December 2024, the organising committee replaced ten medal events from the finalist list announced in October 2024 with new events across various sports, including dragon boat, rhythmic gymnastics, judo, esports, pencak silat, and woodball. Additionally, one medal event was removed from mountain biking, while six new medal events were introduced in athletics, road cycling, and sailing. As a result, the total number of events increased to 574, still falling short of the previous record of 580 set at the 2023 SEA Games in Phnom Penh, Cambodia.
During the first SEAGF coordination committee meeting for the 2025 SEA Games in February 2025, the organising committee approved the inclusion of mixed martial arts (MMA) in the Games, following a request from the SEA Games Federation. It was added under a new category called "value creation sports'". This decision arose from an agreement among Thailand, Malaysia, and Singapore—the hosts of upcoming SEA Games—which mandates that only sports featured in the current edition can be included in future events. Therefore, MMA was introduced to secure its eligibility for future competitions. However, it will not contribute to the official medal tally, as it is designated as a demonstration sport.
==== Sports programme ====
The fifty-sport programme of the 2025 SEA Games surprised the Olympic Council of Asia (OCA) by including the most internationally recognised sports, with 49 out of the 50 sports also contested in the Olympic Games, Asian Games, and Asian Indoor and Martial Arts Games. This marks a historic first for the SEA Games.
Surfing was the only core Summer Olympic sport to not be included in these games. Canoeing and rowing, as well as skateboarding and sport climbing, were combined into single categories, reducing the total count to twenty-eight sports. Additionally, two Winter Olympic sports were featured: ice hockey and ice skating, with figure skating and short-track speed skating categorised together. Furthermore, three optional sports for the 2028 Summer Olympics—baseball/softball, cricket, and squash—were also included, bringing the total number of Olympic sports in these games to thirty-three.
Moreover, six sports included in the programme of the 2026 Asian Games—esports, jujitsu, kabaddi, karate, sepak takraw, and wushu—were added. In addition, twelve sports that were originally planned for the canceled 2021 Asian Indoor and Martial Arts Games were also incorporated, including billiards/snooker, bowling, chess, floorball, futsal, indoor hockey, kickboxing, muaythai, netball, pencak silat, pétanque, and teqball. However, futsal and indoor hockey were categorised under their respective parent sports, football and hockey, respectively, reducing the count of these additional sports to ten.
In addition, ten more sports were added—aquathlon, baseball5, chinlone, dragon boat, duathlon, hockey5s, jet skiing, practical shooting, water skiing/wakeboarding, and woodball—that were not included in the upcoming Olympic and Asian Games, nor the canceled Asian Indoor and Martial Arts Games, but were featured in the upcoming World Games, Youth Olympic Games, as well as in past Asian Games and SEA Games. Baseball5, along with hockey5s, and aquathlon combined with duathlon, are categorised under their parent sports, such as baseball, hockey, and triathlon. Dragon boat, along with jet skiing combined with water skiing/wakeboarding, chinlone, and practical shooting, fall under related sports such as canoeing and rowing, extreme sports, sepak takraw, and shooting, with woodball being the only independent sport included.
Numbers in parentheses indicate the number of medal events contested in each discipline.
Notes
=== Closing ceremony ===
The closing ceremony of the 2025 SEA Games is scheduled to held on 20 December 2025 at Rajamangala Stadium, Bangkok. The SEAGF flag will be handed over to Malaysia, the host country of the 2027 edition. The handover segment will include performances by Malaysia artistes Marsha Milan, Amir Jahari, and Mimifly.
== Participating National Olympic Committees ==
All eleven National Olympic Committee (NOC) members of the Southeast Asian Games Federation (SEAGF) are expected to take part in the games.
Since its debut in 2003, Timor-Leste will participate for the first time as a full ASEAN member state, with its official access to the association since 26 October 2025.
Numbers in parentheses indicate the number of delegations representing in each NOC.
=== Athlete eligibility rules ===
During the Chef de Mission meeting in August 2025, the Organizing Committee confirmed that gender verification tests would be conducted for athletes. The procedures and methods for testing are determined by each individual sports federation, as the Southeast Asian Games Federation (SEAGF) operate independently and are not governed by the Olympic Council of Asia (OCA). All regulations regarding testing are set by the Organizing Committee.
In addition, strict passport verification will be implemented for all athletes, following complaints from some member nations. This comes in response to incidents at the 2023 SEA Games, where some Cambodian naturalised athletes competed using documents other than their national passports, with certificates issued by their respective nations allowing participation. For the 2025 Games, athlete documentation will be thoroughly checked upon entry into Thailand, during the competition, and upon departure. Any cases of document falsification or attempts to field athletes representing countries other than their own will result in immediate action, preventing such violations from occurring during this edition of the Games.

=== Design competition ===
The Sport Authority of Thailand (SAT) originally organised a design competition for the emblem, motto, and mascot for the 2025 SEA Games and the 2025 ASEAN Para Games. The submitted designs were required to be visually appealing, modern, unique, and reflect Thai identity. The submission period was from 20 September to 25 October 2023. The official awarding ceremony took place at the Chaloem Phrakiat Building at the Hua Mak Sports Complex in Bangkok on 23 November 2023.
=== Emblem ===
The official emblem for the 2025 SEA Games, designed by Teeranop Wangsillapakun, the creative director and founder of TNOP Design, was commissioned by the Design Subcommittee of the Thailand Creative Culture Agency (THACCA) under the National Soft Power Strategy Committee.
The emblem embodies the concept of Play by the Rules, drawing inspiration from the principles of rules, discipline, and fair play in sports. It emphasises how creativity and strategy can lead to exceptional achievements within set boundaries. The design seamlessly merges the structured lines of a sports field with the intricate grid patterns of traditional Thai art, capturing both the spirit of competition and the elegance of Thai culture in a modern, refined manner.
This emblem replaced an earlier design selected through a competition. The initial emblem, created by Ruengwit Phutharaporn, was inspired by the pla kat, or Siamese fighting fish, Thailand's national aquatic animal.
=== Motto ===
The official motto for the 2025 SEA Games, Ever Forward (Thai: ก้าวไปข้างหน้าไม่หยุดยั้ง, RTGS: Kaopai Khangna Mai Yutyang, pronounced [kâːwː.pāj kʰâːŋ.nâː mâj jùt.jáŋ]), replaced the previous winning slogan from a design competition, Amity of ASEAN, designed by Phonchit Sachaiyan. Notably, it bears a resemblance to the motto of the Asian Games, Ever Onward, which was established by Guru Dutt Sondhi, the founder of the games.
=== Mascots ===
The official mascots for the 2025 SEA Games, designed by Teeranop Wangsillapakun, the creative director and founder of TNOP Design, were commissioned by the Design Subcommittee of the Thailand Creative Culture Agency (THACCA) under the National Soft Power Strategy Committee.
The mascots consisted of a group of five characters called The San, each vibrant and full of energy. They came in red, green, pink, yellow, and blue, representing the diversity of Thai society. Each character was designed using geometric patterns inspired by the structural lines of traditional Thai motifs, blending modernity with Thai identity. Together, they symbolised celebration, creativity, cultural connection, and the promotion of diversity in sports and society.
On 7 October 2025, a new version of The San was revealed; the number of mascots was reduced to one, with Chan being retained. It was also recoloured to the Thai flag, to represent national pride. The original five San designs would be retained for merchandise.
These mascots replaced an earlier design selected through a competition. The initial mascot, named Mawin, was designed by Tawich Jitthiang and depicted a Waree Kunchorn, a mythical creature from the Himavanta. This creature has the body of an elephant, along with fish-like features, including fins along its backbone, leg fins attached to each of its four legs, and a fishtail.

=== Theme song ===
The official theme song of the Games was "1%", performed by Violette Wautier, F.Hero in Thai version and TWOPEE in English version.
== Concerns and controversies ==
=== Organisational issues ===
==== Ban and reinstatement of pétanque ====
The Thailand Pétanque Association (PAT) was initially sanctioned by the World Pétanque and Bowls Federation (WPBF) and the Fédération Internationale de Pétanque et Jeu Provençal (FIPJP) due to issues regarding the association president's qualifications, which prevented Thai athletes from participating in international competitions. In response, the Sports Authority of Thailand (SAT) established a central committee to oversee athlete selection and organise pétanque for the 2025 SEA Games.
Conflicts arose over athlete selection, as the SAT continued to support athletes from the original association, delaying any resolution. In September 2025, WPBF and FIPJP formally banned the organisation of pétanque events at the Games and announced that any nation sending athletes to compete would face a two-year suspension from all international competitions. Then, Pimol Srivikorn, President of the National Olympic Committee of Thailand (NOCT), and Chaiyapak Siriwat, Vice President of the NOCT, traveled to WPBF and FIPJP headquarters in Paris, France, to negotiate with WPBF and FIPJP to resolve the issue. Concurrently, Deputy Prime Minister Thamanat Prompow sent a letter affirming the Thai government's commitment to follow FIPJP guidelines and support the inclusion of pétanque in the 2025 SEA Games. The SAT also issued clarifications addressing prior communication errors that had caused misunderstandings. Following these actions, WPBF and FIPJP President Claude Azéma approved the inclusion of pétanque at the 2025 SEA Games, allowing the sport to proceed as planned.
==== Basketball player eligibility ====
Philippine Olympic Committee president Bambol Tolentino has been frustrated on the organisers' inability to finalise the eligibility rules on the basketball tournament as of 28 November 2025, derailing the preparations of the Philippine national teams.
In August 2025, it was reported that players only needed to have the appropriate passport; however, this was only clarified in November. The Philippine Basketball Association submitted rosters assuming such rules are to be in effect over the standard FIBA eligibility rules.
On 24 November 2025, it was confirmed that naturalised players as well as any other player who obtained the relevant passport after age 16 are not eligible to play in the standard 5x5 tournaments. This is stricter than the FIBA eligibility rules which allows at least one player satisfying either criteria to be on a roster.
==== National anthem error ====
During the first match of the men's football game between Vietnam and Laos, a technical error prevented the national anthems of both team from being played as scheduled at Rajamangala Stadium.
The governor of the Sports Authority of Thailand, Dr. Kongsak Yodmanee, acknowledged full responsibility for the mistake and expressed a “deepest apologies” for the incident. The committee also ensured such issues will never happen again throughout the tournament.
==== Flag display error ====
In their official website, the organizing committee displayed the wrong flags for the Futsal competition, where they used the Vietnamese flag to represent Thailand, while the Indonesian flag was replaced by Laos.
The organizing committee of the 33rd SEA Games made another serious error when they mistook the Singapore flag for the Indonesian flag at the opening ceremony on the evening of December 9. In particular, in the section looking back at the history of the SEA Games broadcast on the big screen at the opening ceremony of the 33rd SEA Games on the evening of December 9, when introducing the 1997 SEA Games held in Indonesia, the organizing committee of the host country Thailand used the Singapore flag that was taken from footage of the 1997 opening ceremony.
=== Political and diplomatic issues ===
==== Political crisis ====
==== Participation of Cambodian athletes ====
The potential participation of Cambodian athletes in the 2025 SEA Games became a subject of controversy amid the 2025 Cambodian–Thai border crisis. In July 2025, Sorawong Thienthong, Chairman of the Organizing Committee and Minister of Tourism and Sports (MOTS) at the time, suggested the possibility of banning Cambodia following a cross-border attack that resulted in Thai casualties. However, Chaiyapak Siriwat, President of the Southeast Asian Games Federation (SEAGF), emphasised that Thailand, as host of the SEA Games, had no authority to bar Cambodia or any member nation from participating, as decisions must comply with the Olympic Charter, which upholds political neutrality, non-discrimination, and the right of all nations to compete.
Cambodia initially submitted an entry of 1,515 athletes and officials before the clashes, though reports later claimed the number had been reduced to 57. Vath Chamroeun, Secretary General of the National Olympic Committee of Cambodia (NOCC), denied the reports, stating that Cambodia would send a larger contingent. At the Chef de Mission meeting in August 2025, Chaiyapak confirmed that Cambodia had registered around 600 athletes and more than 100 officials. Due to security concerns, however, the Organizing Committee requested that Cambodia reduce its delegation to no more than 200 athletes to ensure adequate safety arrangements. Following a second round of clashes on 8 December and their participation in the opening ceremony the next day, Cambodia withdrew all athletes from the competition on 10 December, citing political and safety concerns.
