The Formula 3 Brazil Open, also known as the F3 Brazil Open, was an annual open wheel racing event at the grand prix circuit of Autódromo José Carlos Pace (Interlagos) in São Paulo, Brazil.

The inaugural meeting took place in January 2010.

The rules and regulations are the same as used in the long-running Formula Three Sudamericana series, using Dallara chassis fitted with 260 bhp Berta engines and Pirelli tyres.
