The 2023–24 AFC Cup was the 20th edition of the AFC Cup, Asia's secondary club football tournament organized by the Asian Football Confederation (AFC), and the final edition under the AFC Cup title, as the competition was revamped under the name AFC Champions League Two starting in 2024–25. This was the first AFC Cup season to have a two-year (autumn-to-spring) schedule, unlike the previous all-year-round (spring-to-autumn) schedule.
As the title holders, Al-Seeb qualified for the 2023–24 AFC Champions League playoff stage. So they were unable to defend their title.
Central Coast Mariners won the competition for the first time, defeating Al Ahed 1–0 in the final. Central Coast Mariners' victory meant that Australia became the first nation to have had clubs winning both the AFC Champions League and AFC Cup, following Western Sydney Wanderers' victory in the 2014 AFC Champions League.
