The 2025 SEA Games (Thai: ซีเกมส์ 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]) were an international multi-sport event sanctioned by the Southeast Asian Games Federation (SEAGF). The event took place in December 2025 from the 9th to the 20th and was held 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. 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 hosted the event. Co-host city Bangkok previously hosted 4 times (1959, 1967, 1975, and 1985), 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, resulting in all events that were to be held in Songkhla to be relocated to venues in Bangkok and Chonburi.
