The 2011–12 Primera División season is the 93rd of Costa Rica's top-flight professional football league.
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.
For this season, Brujas changed their name to Orión FC Desamparados.
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.
