Jeonbuk Hyundai Motors were the defending champions, but were defeated by Yangju Citizen in the round of 16.
Jeonnam Dragons defeated Daegu FC in the final on the away goals rule (4–4 on aggregate) to win their fourth cup title. As winners, they qualified for the 2022 AFC Champions League group stage.
