The Mil Milhas Brasil (also known as the Mil Milhas Brasileiras or 1000 Miles of Brazil in Portuguese) is a sports car endurance race held annually in Brazil since 1956.

The Mil Milhas has been held nearly every year since its inception and is one of the longest running motor racing events in Brazil.

Nearly every running has used the Interlagos circuit, but the 1997 and 1999 events were held at Brasília and Curitiba respectively.

Fittipaldi and Gogliano were inspired to found the race after seeing the 1949 Italian Mille Miglia.

The first event was held on November 24–25, 1956, with 31 cars competing at the Interlagos circuit.
