The Liguilla (English: Playoffs) of the Apertura 2012 season was a final knockout tournament involving the top seven teams of the Ascenso MX league. The winner qualified to the playoff match against the Clausura 2013 winner. If the winner of both tournaments was the same team, the team would have been promoted to the 2013–14 Liga MX season without playing the Promotional Final.
The first team in the general table qualified for the semifinals. The six next best teams in the general table qualified to the quarterfinals.
