The Riverside International Speedway is an automobile racing facility at 151 Legion Road in West Memphis, Arkansas.

Its facilities consist of a 0.25-mile (0.40 km) Gumbo clay oval[3] with banked corners, bleacher seating on both straightaways.

The track was built in 1950 and opened June 10 of that year at an estimated cost of $150,000 by C L Montgomery, originally to showcase midget car racing.
