Sonoma Raceway, Motorsports racing track in Sonoma, United States

The Sonoma Raceway is a motorsport racing track in Sonoma, California, that stretches 4 kilometers (2.5 miles) across hilly terrain. The circuit winds through twelve turns, with the landscape rising and falling almost 50 meters (160 feet) between its highest and lowest points.

Sears Point Properties filed a permit on December 19, 1967, for a 2.470 mi road course, and groundbreaking for Sears Point International Raceway took place on August 14, 1968. The dragstrip opened on March 8, 1969, with Don Garlits winning the first Top Fuel event; the road course opened on March 28. Filmways bought the track in 1969, closed it in May 1970, and it reopened in 1973.

NASCAR and IndyCar races draw American motorsport fans, while on other weekends local clubs use the circuit for their own training sessions. The grounds transform into a gathering point for camping enthusiasts who park their RVs between the hills during major events.

The track lies roughly 90 kilometers (57 miles) north of San Francisco and offers space for tens of thousands of spectators. Visitors attending major races should arrive early, as the grounds become much busier and parking can be limited.

The Chute, an 890-foot straight linking turns 4 and 7, was built in 1998 for NASCAR events, bypassing the Carousel turns 5 and 6 and shortening the lap from 2.520 to 1.990 miles. The dragstrip runs a quarter mile uphill, and a 62-foot four-sided electronic display tower went up in the road course's middle in 1994.
