The 2008 Torneo Descentralizado (known as the Copa Cable Mágico for sponsorship reasons) was the ninety-second season of Peruvian football.
A total of 14 teams competed in the tournament, with Universidad San Martín defending their national title.
Deportivo Municipal and Total Clean finished the 2007 season in 11th and 12th place, respectively, in the aggregate table and thus were relegated to the Segunda División.
They were replaced by the champions of the Segunda División 2007 and Copa Perú 2007, Universidad César Vallejo and Juan Aurich.
Sporting Cristal was the other team close to winning the title, however they had three games left to play and would have been unable to reach Universitario.
They lost four games at home and failed to finish in the top 7 to contest the national title.
