The 2013 Campeonato Paranaense de Futebol Profissional da 1ª Divisão was the 98th season of Paraná's top professional football league.
Coritiba won the championship for the 37th time, while Paranavaí and Nacional were relegated.
The tournament consists of a double round-robin format, in which all twelve teams play each other twice, with classification split in two stages.
In case of a tie in number of points and goal balance, the advantage is for the best campaign team.
The best two-placed teams in the overall classification not advancing to the finals and not from Curitiba will face themselves in a two-legged tie competing for the Torneio do Interior.
