# 2021 Korean FA Cup

The 2021 Korean FA Cup, known as the 2021 Hana Bank FA Cup due to sponsorship agreement with Hana Bank, was the 26th edition of the Korean FA Cup. Similar to the previous year, U-League teams did not participate, and the top ten sides from the K5 League gained qualification instead.
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.
