The AFC Cup is an annual continental club football competition organized by the Asian Football Confederation (AFC) . The competition is played primarily between clubs from nations that did not receive direct qualifying slots to the top-tier AFC Champions League, based on the AFC Club Competitions Ranking. The tournament has been dominated by clubs from West Asia, with the only winners from outside that region being Uzbek side FC Nasaf in 2011 and Malaysian side Johor Darul Tazim in 2015. Al-Seeb are the current champions after defeating Kuala Lumpur City in the 2022 final. Since the 2021 season, the team who wins the AFC Cup is granted qualification to the following seasons AFC Champions League qualifying playoffs should they not qualify through their domestic performance. The AFC Cup is set to be discontinued after the end of the 2023–24 season, with the AFC Champions League 2 and AFC Challenge League being introduced as replacements.

It is important to note that the AFC Cup is different from the AFC Asian Cup, which is the primary association football competition contested by the senior mens national teams of the members of the Asian Football Confederation (AFC) . The AFC Asian Cup is held every four years and determines the continental champion of Asia. The winning team becomes the champion of Asia and until 2015 qualified for the FIFA Confederations Cup. The most recent AFC Asian Cup was held in Qatar in 2023.
