The 1977 Campeonato Paulista da Divisão Especial de Futebol Profissional[1] was the 76th season of São Paulo's top professional football league.
Corinthians won the championship for their 16th title.
Serginho Chulapa from São Paulo was the top goalscorer, with 32 goals.
Wins by three goals' difference or more were worth an extra point.
[2][1] In the Third round, the eight remaining teams would be divided into two groups of four, each team playing once against the teams of its own group and the other group, and the best teams of each group qualifying to the Finals.
