The 2013 Campeonato Ecuatoriano de Fútbol de la Serie A (officially known as the Copa Pilsener Serie A for sponsorship reasons) was the 55th season of the Serie A, Ecuador's premier football league. Barcelona was the defending champion.
On the night of January 8, 2013, the Ecuadorian Football Federation determined that the format for 2013 would be the same as the previous season.
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.
