The Autódromo Internacional Nelson Piquet (Nelson Piquet International Autodrome), also known as Jacarepaguá after the neighbourhood in which it was located, was a motorsport circuit in Rio de Janeiro, Brazil. Opened in 1977, it hosted the Formula One Brazilian Grand Prix on ten occasions, and was also used for CART, motorcycle racing and . In 2012, it was demolished to make way for facilities to be used in the 2016 Summer Olympics.
The original circuit was built between 1971 and 1977 on the site of the Barra da Tijuca road course, which had itself been built on reclaimed marshland and was operational from 1964 to 1970. It was a relatively flat circuit, with a long pit straight and a longer back straight (which allowed the turbo-engined Formula One cars of the mid-1980s to reach speeds of 300 km/h (186 mph)), and numerous mid- to slow-speed corners with plenty of room for overtaking. The maximum spectator capacity was 90,000.
The first Brazilian Grand Prix at the circuit took place shortly after opening, in 1978, and was won by Argentina's Carlos Reutemann in a V12 Ferrari 312T3, after Sweden's Ronnie Peterson had taken pole position in the revolutionary ground-effect Lotus 78-Ford.
