Águas de São Pedro–São Paulo 1941 chess tournament
The Águas de São Pedro International Tournament () was a chess tournament held from 2 to 26 July 1941 in Águas de São Pedro and São Paulo. The event, the first international chess tournament of Brazil, was organized by the São Paulo Chess Club and sponsored by Antonio and Octavio Moura Andrade, being the latter founder of Águas de São Pedro and owner of the Grande Hotel.

European masters were invited, as well as South American masters. The representatives of Brazil were selected by the Brazilian Confederation of Chess and the São Paulo Chess Club.

The tournament would begin on June 30, but it was preferred to start the competition on July 2. Most of the matches took place at the Grande Hotel in Águas de São Pedro, but the last four have occurred in São Paulo. Of these four, two occurred in the foyer of the Municipal Theatre, and two occurred at the headquarters of São Paulo Chess Club, on the second floor of the Martinelli Building.

The rules of the tournament were:
