The 2017 AFC Cup qualifying play-offs were played from 30 January to 28 February 2017. A total of 14 teams competed in the qualifying play-offs to decide five of the 34 places in the group stage of the 2017 AFC Cup.
In the qualifying play-offs, each tie was played on a home-and-away two-legged basis. The away goals rule, extra time (away goals would not apply in extra time) and penalty shoot-out were used to decide the winner if necessary (Regulations Article 9.3). The five winners of the play-off round advanced to the group stage to join the 29 direct entrants.
The bracket of the qualifying play-offs for each zone was determined by the AFC based on the association ranking of each team, with the team from the higher-ranked association hosting the second leg. Teams from the same association in the ASEAN Zone could not be placed into the same play-off.
^ abcRovers (Guam) and Taipower (Chinese Taipei) withdrew from the group stage after the draw, and Tatung (Chinese Taipei) withdrew from the qualifying play-offs, and thus Kigwancha (North Korea) and Erchim (Mongolia) advanced directly from the play-off round and preliminary round respectively to the group stage to replace them, and only three teams competed in the East Asia Zone group stage, and the East Asia Zone qualifying play-offs were not played.
^Teams from Afghanistan were not allowed to host their home matches in their country due to security reasons.
