Autódromo Internacional Nelson Piquet is a racing circuit in Brasília, the capital of Brazil. It is 5.476 km in length and hosts a variety of national-level series including Stock Car Brasil, Formula Truck and Formula 3 Brasil. It has previously hosted non-championship rounds for both Formula One and the BPR Global GT Series, and in recent years has been scheduled to host both MotoGP and Indycar, but due to costs and construction delays, neither event went ahead. Previously named Autódromo Emilio Medici and Autódromo de Brasília, the circuit's name was later changed to honor Formula 1 World Champion Nelson Piquet.
