The earliest definition requires winning the Indianapolis 500 (first held in 1911), the 24 Hours of Le Mans (first held in 1923), and the Formula One World Drivers' Championship (first held in 1950). Under a more recent popular definition, the World Drivers' Championship is replaced by the Monaco Grand Prix (first held in 1929). Graham Hill is the only driver to have completed the Triple Crown under either definition.
The Indianapolis 500 was a round of the World Drivers' Championship from 1950 to 1960; the Monaco Grand Prix has been included from 1950 to the present.

From 1971 to 1989, IndyCar contested its own Triple Crown of three 500-mile events. From 1971 to 1980 these were the Indianapolis 500, the Pocono 500, and the California 500 at Ontario Motor Speedway. After Ontario closed in 1980, the California 500 was replaced by the Michigan 500. The format ran through 1989 before the Pocono race was discontinued. Six drivers achieved the career feat across all variations: Bobby Unser, A. J. Foyt, Al Unser, Johnny Rutherford, Danny Sullivan, and Rick Mears. Al Unser is the only driver to win all three in a single season, in 1978. The IndyCar Triple Crown was revived in 2013 with the Indianapolis 500, the Pocono 500, and the MAVTV 500 at Fontana, carrying a $1 million bonus prize. Fontana was removed from the IndyCar calendar after 2015 and Pocono after 2019.

Both the Winternationals and the Auto Club Finals are held at Auto Club Raceway at Pomona. John Force holds the most Triple Crown wins in the Funny Car division.
