The Monterey Grand Prix (formerly run under various names) is a sports car race held annually at Mazda Raceway Laguna Seca. The event began in 1950 as a race on the roads of Pebble Beach, California. In 1951, it was added to the new SCCA National Sports Car Championship. When Laguna Seca Raceway was built in 1957, the races moved there. The event fell dormant after the National Championship was discontinued in 1957, but was revived by the SCCA's new United States Road Racing Championship in 1963. The race fell dormant again in 1969, and was revived in 1973 with the IMSA GT Championship.
