The Primera División Peruana, also known as Torneo Descentralizado, is Perú’s top football category in that country. The championship is divided into three tournaments: Torneo de Verano, Torneo Apertura, and Torneo Clausura. The winner of each competition and the club with the most added points enter a playoff stage. The winner of each tie plays for the national championship.

The overall standings determine three teams that enter the Copa Libertadores (one makes it to the group stage, while two more enter the preliminary rounds). Teams ranked 4th to 7th enter the first stage of the Copa Sudamericana. Furthermore, the winners of the Apertura and Clausura tournaments earn a spot in the Copa Libertadores.

Promotion and relegation rules are quite unique in this competition. The overall standings determine relegation, as the two worst teams of each season are sent to the Segunda División. The winner of the Segunda División is promoted to the Peruvian top flight, while the winner of the Copa Perú joins them as the second promoted team each season.

The Torneo Descentralizado 2017 saw Alianza Lima winning the title since they won the Apertura and Clausura tournaments. Juan Aurich and Alianza Atlético were relegated to the Segunda División, leaving their spots to Sport Boys and Binacional.

The 2018 Torneo Descentralizado began on February 3, 2018. The end of this competition will be determined once all games of the Torneo Clausura are played.

Did you know? Sporting Cristal and Universitario are the joint most-winning teams in the Peruvian top flight, having won 16 titles apiece.
