Rodoanel Mário Covas (official designation SP-021) is the planned (and partially built) beltway of the Greater São Paulo, Brazil. Upon its completion, it will have a length of 177 km (110 mi), with a radius of approximately 23 km (14 mi) from the geographical center of the city. It was named after Mário Covas, who was mayor of the city of São Paulo (1983–1985) and a state governor (1994-1998/1998-2001) until his death from cancer. It is a controlled access highway with a speed limit of 100 km/h (62 mph) under normal weather and traffic circumstances.

The first section was inaugurated in October 2002, starting at the Estrada Velha de Campinas (lit. Old Road of Campinas), in the northern part of São Paulo, and ending at the Régis Bittencourt highway, in Embu, covering 32 km (20 mi). It crosses Anhangüera, Bandeirantes, Castelo Branco, and Raposo Tavares highways. There are urban accesses to the cities of Osasco and Carapicuíba, but it also crosses through the municipalities of Barueri, Santana de Parnaíba, Embu, Cotia, and São Paulo. The current segment has three tunnels, one of them being the largest and widest one in Brazil, with 1.6 km (0.99 mi), 62 viaducts and six bridges.
