São Paulo/Guarulhos–Governor André Franco Montoro International Airport (IATA: GRU, ICAO: SBGR), commonly known as São Paulo/Guarulhos International Airport, is the primary international airport serving São Paulo. It is popularly known locally as either Cumbica Airport, after the district where it is located and the Brazilian Air Force base that exists at the airport complex, or Guarulhos Airport, after the municipality of Guarulhos, in the state of São Paulo, where it is located. Since November 28, 2001, the airport has been named after André Franco Montoro (1916–1999), former Governor of São Paulo state. The airport was rebranded as GRU Airport in 2012.

The airport was the busiest in Brazil in terms of transported passengers, aircraft operations, and cargo handled in 2012, placing it as the second busiest airport in Latin America by passenger traffic (41.307.915 2023) after Mexico City International Airport. Guarulhos has slot restrictions, operating with a maximum of 45 operations/hour and being one of the five airports with such restrictions in Brazil (the others are São Paulo-Congonhas, Brasília, Belo Horizonte-Pampulha and Rio de Janeiro-Santos Dumont).

Since 2012, the airport has been operated by a consortium composed of Invepar S/A, Airports Company South Africa, and Infraero.

Some of its facilities are shared with the São Paulo Air Force Base of the Brazilian Air Force.
