The Circuit Riverside Speedway Ste-Croix is a multi-track motorsport venue located in Sainte-Croix, Quebec (Canada), approximatively 60 km west of Quebec City, on the south shore of the St. Lawrence River.

The facility features a 5/8-mile length oval speedway and a 1,7 km 9-turn road course.

The configuration of the oval track, long straights with tight curves, reminiscent of the famous Martinsville Speedway in Virginia.

The track opened in 1971 but closed just three years later in 1974 due to financial problems.

The original road course was of 2.5 km length, using the oval track and climbing the hill near Route 132.
