Riverside International Raceway, Motorsport racing track in Riverside, California, US

Riverside International Raceway was a motorsport circuit near the San Bernardino foothills in Riverside, California, that ran through several miles of desert landscape with long straights and steep elevation changes. The track layout included uphill corners and banked sections that could be reconfigured depending on the racing series.

Rudy Cleye and John Campbell Edgar built the track through their West Coast Automotive Testing Corporation, completing it in 1957 after a San Bernardino County proposal failed. It hosted the 1960 United States Grand Prix, won by Stirling Moss, and NASCAR and IMSA events until 1989. Demolition began in June 1988, and the site became the Moreno Valley Mall shopping district.

The track's proximity to Los Angeles made it a frequent filming location for television shows including The Rockford Files and Knight Rider during the 1970s.

The circuit site is now occupied by a shopping district centred on the Moreno Valley Mall, so there is no track left to walk. The former course lay in Moreno Valley, reached by U.S. Route 60 and what is now Interstate 215. Look for the wide sign over the old track line in period photographs rather than on the ground.

The circuit hosted a single Formula One World Championship race, the 1960 United States Grand Prix on 20 November. Stirling Moss started from pole in a Lotus 18 with a qualifying time of 1:54.4 and won; Jack Brabham set the fastest lap, 1:56.3, in a Cooper T53 on lap 71.
