Host selection Hosting duties are rotated among the member countries of the SEA Games Federation. Each member country is assigned a specific year to host the event, but they have the option to withdraw or opt out of hosting for that particular edition.
2019 disruption On the 21st of July in 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 insistence on handling all aspects of the hosting—including finances, security, and the organization of the Games, similar to how it managed the
2005 SEA Games—contributed to the PSC's decision to withdraw its support. On the 10th of August in 2017, Charouck Arirachakaran, the Vice President and Secretary General of the
National Olympic Committee of Thailand, 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, Philippine Olympic Committee President
Peping Cojuangco confirmed that it would still 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 SEA 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—the original term for the SEA Games—in
1959, and subsequently in
1967 and
1975, as well as in
1985 after the event had become known as the SEA Games. The
1995 and
2007 editions were held in the Thai provinces of Chiang Mai and
Nakhon Ratchasima, respectively.
Bidding and election On the 11th of October in 2022, Chaipak Siriwat, the Vice President of the National Olympic Committee of Thailand, revealed the framework for the bidding process for the 2025 SEA Games. He emphasized that the host cities or provinces should aim to organize 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 Vice Governor of the
Sports Authority of Thailand Prachum Boontiem nominated eight bidding parties from twelve cities or provinces interested in hosting the 2025 SEA Games. The city of Bangkok as well as the provinces of Chiang Mai,
Nakhon Ratchasima, and Songkhla submitted sole bids, while the Bangkok Metropolitan Region,
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 the 13th of January in 2023, the Sports Authority of Thailand selected three provinces—
Bangkok Metropolitan Region,
Chonburi province, and
Songkhla province—to host the 33rd SEA Games, while the
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 had been signed.
Handover ceremony 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 the 17th of May in 2023 at the
Morodok Techo National Stadium. 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 the 7th of December in 2024.
Sorawong Thienthong, Chairman of the Organizing Committee and
Minister of Tourism and Sports, announced that the 2025 SEA Games and the 2025 ASEAN Para Games would be held under the themes of
Green SEA Games and
Sustainable Paralympics. The games aimed to achieve
net-zero emissions by promoting
eco-friendly transportation, utilizing
sustainable products, and selecting venues that prioritized
environmental protection. This
environmentally friendly vision would also be implemented in the
2025 FIVB Women's Volleyball World Championship held in August 2025.
Venues The 2025 SEA Games utilized 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. The Bangkok Metropolitan Region, which includes the city
Bangkok and the neighboring provinces of
Nakhon Pathom,
Nonthaburi,
Pathum Thani,
Samut Prakan, and
Samut Sakhon, hosted the majority of the 42 sports. Meanwhile, Chonburi hosted 15 sports on its own. Only three events took place in outlying venues: men's football preliminaries held in
Chiang Mai, skeet shooting in
Ratchaburi, and road bicycle racing in
Nakhon Nayok and
Prachinburi. Originally, Songkhla province was intended to host 10 events; The original intended venues for the events intended for Songkhla (and other moved events) are denoted in the footnotes for this section. ;Bangkok cluster ;Chonburi cluster ;Outlying venues
