2011–12 Costa Rican Primera División season

The 2011–12 Primera División season is the 93rd of Costa Rica's top-flight professional football league. The season was divided into two championships: the Invierno and the Verano. The season began on 31 July 2011.

Promotion and relegation
Universidad de Costa Rica finished last season in last place in the overall table at the end of last season and were relegated to the Segunda División. Replacing them in the league for this season are the overall champions of last season's Segunda División competition, Belén Siglo XXI.

Barrio México were expelled from last year's competition during the 2011 Verano tournament and were eventually relegated from the league due to various financial difficulties. They were not replaced for this season.

For this season, Brujas changed their name to Orión FC Desamparados.

Format changes
Due to the reduction of the league to 11 teams for this season, the league's format was changed for this season. There would be no groups this season. Instead, for both tournaments, the clubs would play every other club twice, once at home and once away, for a total of 20 matches each. At the end of the regular season, the top 4 teams in the league standings would participate in the playoffs. At the end of the season, the last place club would participate in a promotion-relegation playoff against the Segunda División overall runners-up, while the Segunda División overall champions would be promoted to next season's competition automatically.
