The ASEAN Championship (formerly known as the AFF Championship or AFF Cup), currently known as the ASEAN Hyundai Cup for sponsorship reasons, is the biennial football tournament organised by the ASEAN Football Federation (AFF) for men's national teams in Southeast Asia. A biennial international competition, it is contested to determine the sub-continental champion of Southeast Asia. The competition has been held every two years since 1996, scheduled to be in the even-numbered year, except for 2007, and 2020. Four national teams have won the ASEAN Championship title; Thailand has won seven titles, Singapore four, Vietnam three, and Malaysia one. To date, Thailand and Singapore are the only teams to have won consecutive titles. Thailand did it three times: in 2000, 2002, 2014, 2016, 2020, and 2022, while Singapore did it once in 2004 and 2007. Australia, an AFF member since 2013, has not played the ASEAN Championship. It is one of the most watched football tournaments in the region. The ASEAN Championship is recognised as an 'A' international tournament by FIFA with FIFA ranking points being awarded since 1996. Since 2018, the championship winners would compete in the following AFF–EAFF Champions Trophy, against the winner of the EAFF E-1 Football Championship (East Asia). The defending tournament champions are Vietnam, after a 5–3 aggregate victory over Thailand in the 2024 ASEAN Championship final. FIFA president Gianni Infantino announced the launch of the FIFA ASEAN Cup on 26 October 2025 during the 2025 ASEAN Summits in Kuala Lumpur, although no further details about its format were disclosed until FIFA approved on 20 March 2026.
