This page provides the summaries of the matches of the playoff stage of the Asian football qualifiers for 2012 Olympics.
The three runners-up from the third round groups will play each other at a neutral venue on 25, 27 and 29 March 2012 (tie-breaking play-off on 31 March if necessary). Malaysia had originally been chosen but renovations to the proposed stadium as well as the unavailability of other venues due to the scheduling of domestic fixtures meant that a new destination for the three-team playoffs was required. Vietnam was later chosen by the AFC Competitions Committee as the neutral venue, with games to be played at Hanoi's My Dinh National Stadium
The winner of this group will advance to play the fourth-ranked team of the African qualification tournament in a play-off for a spot at the Olympic Games.
