The –MexicanPrimeraDivisió2011–12 Primera División Profesional season was the 65th professional top-flight football league season in Mexico. The season was split into two tournaments: the Torneo Apertura and the Torneo Clausura; each of identical format and contested by the same eighteen teams.
Changes from 2010–11
On May 16, 2011, the General Assembly of the Primera División announced a format change to begin with the 2011 Apertura. The first change was the elimination of groups in the First Stage. The top eight teams at the end of the First Stage would advance to the next round. The other change would affect the playoffs. Instead of a two-legged, single elimination tournament culminating in the finals, the eight teams in the next round would be placed into two groups of four. The four teams in each group will play against other in a double round-robin format. The top team in each group will advance to the Finals. However, on June 6, 2011, the Primera División Profesional's Operations Committee announced that the format change would only affect the elimination of groups in the First Stage, and that the playoffs would remain as they were. Therefore, the top eight teams at the end of the First Stage would advance to a two-legged elimination bracket.
Clubs
The following eighteen teams participated in the season. Necaxa was relegated to the Liga de Ascenso after accumulating the lowest coefficient during the immediate past three seasons, ending its one-year stay in the league. Tijuana was promoted, the winner of the 2010–11 Liga de Ascenso season. This is Tijuana's inaugural season in the Primera División.
