2021 AFC Cup group stage


The 2021 AFC Cup group stage was played from 14 May to 24 August 2021. A total of 38 teams should have competed in the group stage to decide the 12 places in the knockout stage of the 2021 AFC Cup.

Draw


The draw for the group stage was held on 27 January 2021, 14:30 MYT, at the AFC House in Kuala Lumpur, Malaysia. The 38 teams were drawn into nine groups of four and one group of three : three groups each in the West Asia Zone and the ASEAN Zone, two groups in the Central Asia Zone, and one group each in the South Asia Zone and the East Asia Zone. For each zone, teams were seeded into four pots and drawn into the relevant positions within each group, based on their association ranking and their seeding within their association, in consideration of technical balance between groups. Teams from the same association in zones with more than one group could not be drawn into the same group.

Originally, 39 teams entered into the group stage draw, which included the 35 direct entrants and the four winners of the play-off round of the qualifying play-offs, whose identity was not known at the time of the draw. However, after the withdrawal of teams from Oman and Myanmar, and promotion of Kaya–Iloilo to AFC Champions League group stage, only 37 teams would compete, including 34 direct entrants, one winner of the play-off round, and two winners of the preliminary round.
