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.

Águas de São Pedro
To promote the development and exploitation of the medicinal waters in an economically viable way, Octavio Moura Andrade conceived and designed a city focused on hydrotherapy and residential purposes: a spa town. Águas de São Pedro was created as a hydromineral spa, fully planned and aiming to serve both those who needed treatment and tourists looking for fun and leisure. The urban planner Jorge de Macedo Vieira was chosen to integrate the use of space with the mineral waters, topography, soil, and climate, conducting a two-year-long detailed study of the area prior to designing the city. It was only in 1940 that the project was completed, being recorded in the Real Estate Registry Office of the District of São Pedro under number1, in accordance with the requirements of the Brazilian Federal Decree-Law No.58, of 10 December 1937.
