The Taça Ioduran (English: Ioduran Cup), 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.

[1] In two of the three editions of the competition, the result was decided by W/O.

This was because CA Paulistano refused to face America in 1917 and Fluminense in 1919.
