The 2012 Campeonato Paranaense de Futebol Profissional da 1ª Divisão was the 97th season of Paraná's top professional football league.
Coritiba won the championship for the 36th time, while Roma Apucarana and Iraty 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.
The finals are notable in the sense that goal difference will not be a tiebreaking criterion; if both teams tie on points the decision will go directly to a penalty shootout.
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.
