The 2000 season of the Torneo Descentralizado was the 85th season of the top category of Peruvian football (soccer). It was played by 12 teams. The national champion was Universitario.
The national championship was divided into two tournaments, the Torneo Apertura and the Torneo Clausura. Each was played on a home-and-away round-robin basis. The winners of each would play for the national title in a play-off, but since the same club had won both tournaments, it automatically won the national championship.
Following-season Copa Libertadores berths went to the champion, as well as to each of the half-year tournament's runners-up, who held a play-off as a formality to decide the overall season runners-up. The bottom team on the aggregate table was relegated, while the eleventh place team held a promotion play-off against the winner of the Segunda División (Second Division).
Before the start of the season, Deportivo Pesquero relocated from Chimbote to Huancayo and changed its name to Deportivo Wanka.
No final for the championship title was contested after Universitario won both the Apertura and Clausura tournaments, thus automatically becoming national champions.
