The 2021 AFC Cup was the 18th edition of the AFC Cup, Asia's secondary club football tournament organized by the Asian Football Confederation (AFC).[3]
The winners of the tournament automatically qualified for the 2022 AFC Champions League, entering the qualifying play-offs, if they had not qualified through their domestic performance.[4]
Lebanese club Al-Ahed, having won their first AFC Cup title in 2019, were the title holders, since the 2020 edition was cancelled due to the COVID-19 pandemic in Asia after several group stage matches and the title was not awarded. However, Al-Ahed were eliminated by the eventual winners Al-Muharraq in the West Asia Zonal semi-finals.
