Autódromo Internacional Nelson Piquet, Motor racing circuit in Brasília, Brazil

The Autódromo Internacional Nelson Piquet is a 5,475.58 m clockwise circuit on flat ground in Brasília, with six left-hand and six right-hand corners and a 750 m main straight. Its grey asphalt loop is broken by two roundabout interchanges with circular infield islands, and inside the loop a broad grassy field holds a circular paved pad marked with tyre tracks and old tyres laid flat.

The circuit opened in 1974 as Autódromo Emilio Medici and passed through several changes in management over the years. It was later renamed to honor Brazilian racing champion Nelson Piquet.

The circuit's name honours Nelson Piquet, who grew up in Brasília and became a three-time Formula 1 world champion; it was renamed after his 1987 title. Within the grounds operate the Ferrari Kart kart track, built in 2003, and the Cine Drive-in, the last drive-in cinema of its kind in Brazil. The venue has also hosted music shows and vehicle exhibitions.

The circuit sits in the Setor de Recreação Pública Norte, across the road from the Estádio Nacional and the Nilson Nelson Gymnasium. The track has been closed since 2014, so there are no races to attend; the asphalt was torn up during the halted renovation. Inside the grounds still operate the Ferrari Kart karting track, built in 2003, and the Cine Drive-in, the last of its kind in Brazil.

The circuit's 5,475.58-metre layout has six left-hand and six right-hand corners, with the longest straight reaching 750 metres. Rubens Barrichello has called the layout the best Brazil has, and journalist Reginaldo Leme describes it as highly technical. Within the grounds also operate the Ferrari Kart track, built in 2003, and the Cine Drive-in, the last of its kind in Brazil.
