1913 Campeonato Paulista

In the 1913 season of the Campeonato Paulista, two championships were played, each by a different league.

APSA Championship
Before the start of the 1913 championship, a split happened within the LPF - Paulistano left the league, uncomfortable with the growing inclusion of lower-class teams, like Ypiranga and the recently-joined Corinthians, in the league, in addition to the fact that the league moved its official playing field to the Parque da Antarctica Paulista (which was used by Germânia), in detriment to their own stadium, the Velódromo Paulistano, and was joined by AA das Palmeiras and Mackenzie. The new league would be called the APSA (Associação Paulista de Sports Athleticos). Paulistano won the title for the 3rd time. Three players shared the top scorer position, with 3 goals each.

The championship was disputed in a triple-round robin system, with the team with the most points winning the title.
