1975 Torneo Descentralizado
The 1975 season of the Torneo Descentralizado, the top category of Peruvian football, was played by 18 teams. The top six qualified to the final group stage. As the First Division was reduced to 16 teams for 1976, no team was promoted and two teams were relegated. The criteria for relegation: Grau as the last placed team; Unión Tumán as the worst team from a Department with two teams. This rule didn't apply for Lima clubs. A playoff match for 2nd place was necessary. The national champions were Alianza Lima.Teams
