Primera División de Costa Rica is a professional league for association football clubs in Costa Rica. At the top of the Costa Rican league system, it is the country's primary football competition. Contested by 12 clubs, it operates on a system of promotion and relegation with Segunda División. The seasons are separated by two single tournaments each year, the Apertura, from July to December, and the Clausura, from January to May. Thus, there are two champions each season with teams playing anywhere from 32 to 44 games each, totalling 412 games in the season. Most games are played on Saturdays and Sundays, but recently there have been games programmed on Friday afternoons and Monday nights. Also the league has some Wednesday nights available to program games if any club needs it. The Campeonatos de Invierno and Verano are sponsored by Junta Protección Social-ProGol.
The competition formed on June 13, 1921 following an invitation presented by Guatemala to Costa Rica to participate in its Centenary Games. A total of 12 clubs have won the title. The current champions are Alajuelense, who won the 2013 Campeonato De Invierno.
