The Autodrome Montmagny is a multi-track motorsport venue located in Montmagny (Canada), approximately 80 km (50 mi) east of Quebec City.
Inaugurated in 1994, it was originally a 0.500 mi (0.805 km) oval dirt track.
The racetrack was the property of the American stock car driver Ralph Nason for a decade before being sold to local owners in 2010.
The track hosts stock car races (Quebec's ACT Series, PASS North, Sportsman Quebec) and drift competition (Drift Mania Canadian Championship).
It is scheduled to host the season finale of the NASCAR Canada Series since 2024.
