Taça Ioduran
The Taça Ioduran (), was the third interstate clubs competition realized in Brazil, after Taça Salutaris (1911), and Taça dos Campeões Estaduais (1913 and 1914). The tournament consists of the clash between São Paulo champions and Rio de Janeiro champions. In two of the three editions of the competition, the result was decided by W/O. This was due to the fact that CA Paulistano refused to face America in 1917 and Fluminense in 1919. List of Champions
