The knockout stage of 2022 AFC Women's Asian Cup began on 30 January 2022 with the quarter-finals and ended on 6 February 2022 with the final in Navi Mumbai, India.[1]
In the knockout phase, if a match is level at the end of 90 minutes of normal playing time, extra time is played (two periods of 15 minutes each), where each team is allowed to make a fourth substitution.[2] If still tied after extra time, the match is decided by a penalty shoot-out to determine the winners.[2] From this tournament, there will be no third place play-off.
^Due to non-compliance with conditions set by the World Anti-Doping Agency (WADA), Thailand was not allowed to be represented by their national flag.[3] The sanctions took effect in October 2021.[4] Thailand was represented by its national team logo.[5] Sanctions were lifted on 4 February[6] and Thailand was able to use their flag in time for their last playoff match against Chinese Taipei.[7]

The format of the play-offs round depended on the performance of Australia, who qualified automatically for the World Cup as hosts.[12] Since Australia was eliminated in the quarter-finals, the play-offs format was for the remaining three quarter-final losers to play a single round-robin play-off. The best team after three matches advanced to the World Cup, and the remaining two teams entered the inter-confederation play-offs.
