The Liguilla (English: Little League) of the 2011–12 Liga de Ascenso season is a final knockout tournament involving seven teams of the Liga de Ascenso. The winner will qualify to the playoff match vs the Clausura 2011 winner. However, if the winner of both tournaments is the same team, the team would be promoted to the 2012–13 Mexican Primera División season without playing the Promotional Final.
The first team in the general table qualified for the semi-finals. The six next best teams in the general table qualified to the quarter-finals.
