Interlagos is a neighborhood in the city of São Paulo, Brazil. It includes the Autódromo José Carlos Pace race track, home of the Formula One Brazilian Grand Prix. Its name (adapted from Interlaken, Switzerland) comes from the fact that the region is located between two large reservoirs, Guarapiranga and Billings, built in the early 20th century to supply water and electric power to the city. The suburb of Interlagos is located in the south region of São Paulo City to the right edge of the Guarapiranga reservoir.

The Autódromo José Carlos Pace itself is still commonly called Interlagos, although this hasn't been its official name since the 1970s.

The history of the Interlagos circuit dates back to the 1920s, when the city of São Paulo was undergoing a process of fast urbanization.
