Técnico Universitario
Twelve teams will compete in the 2013 Serie A season, ten of whom remain from the previous season. Técnico Universitario and Olmedo were relegated last season after accumulating the fewest points in the 2012 season aggregate table. They will be replaced by Universidad Católica and Deportivo Quevedo, the 2012 Serie B winner and runner-up, respectively. Both teams are making returns to the Serie A. Universidad Católica is returning after two seasons, while Deportivo Quevedo is returning after seven.
