The Circuit Trois-Rivières is a street circuit in Trois-Rivières, Quebec, Canada. The circuit has been the home of the annual Grand Prix de Trois-Rivières, the longest-running street race in North America, since 1967. The circuit is located on the Terrain de l'Exposition (fairgrounds) and is unusual in that it passes through Porte Duplessis, the narrow concrete gateway of the grounds at turn 3. Throughout its history the circuit has hosted numerous major North American racing series including the American Le Mans Series, the Grand-Am Rolex Sports Car Series, the Trans-Am Series, Can-Am, Indy Lights and Formula Atlantic. The Grand Prix has been headlined by the NASCAR Pinty's Series since 2007 (except 2020), and from 2014 until 2019 it was expanded to two weekends when it was joined by the FIA World Rallycross Championship and its World RX of Canada race.
