The AFC Asian Cup is an international association football tournament run by the Asian Football Confederation (AFC). It is the second oldest continental football championship in the world after Copa America. The winning team becomes the champion of Asia and qualifies for the FIFA Confederations Cup.

Since 1972, the final tournament is played in two stages: the group stage and the knockout stage. Since 2019, each team plays three games in a group of four, with the winners and runners-up from each group advancing to the knockout stage along with the four best third-placed teams. In the knockout stage the sixteen teams compete in a single-elimination tournament, beginning with the round of 16 and ending with the final match of the tournament.
