The 2024 ASEAN Championship knockout stage (previously AFF Championship)[1] will be played from 26 December 2024 to 5 January 2025. A total of 4 teams will compete in the knockout stage to decide the champions of the 2024 ASEAN Championship.
All matchup ties will be played over two legs. The team that scores more goals on aggregate over the two legs wins the tie. If the aggregate score is level at the end of normal time of the second leg, the team that scores more away goals across both legs advances. If the away goals are still level, extra time is played (without applying the away goals rule), and if the same number of goals are scored by both teams during extra time, the tie is decided by a penalty shoot-out.
