Buttonwillow Raceway Park is a motorsports park in Kern County, California, 10-mile (16 km) north of the town of Buttonwillow and 28-mile (45 km) northwest of Bakersfield. Opened in 1995, it is owned and operated by the California Sports Car Club, a region of SCCA, Buttonwillow is the "flagship" track of Cal Club, and is also the location of the Club's administrative offices.

The track offers multiple configurations, with the configuration "Race #13 CW" being the most popular. Many time attack series, most notably Super Lap Battle, hold their events with the 13CW configuration.

The Super Lap Battle is a time attack event held at Buttonwillow since 2004.

The track was repaved in July 2014.

A new, technical circuit is scheduled to finish construction in 2023. The addition will include a new tower building, Tesla Supercharger stations, and new garages. The new track will be named as "The Circuit", with the original track being renamed as "The Classic".
