Watkins Glen International, nicknamed "The Glen", is an automobile race track located in the town of Dix just southwest of the village of Watkins Glen, New York, at the southern tip of Seneca Lake. It was long known around the world as the home of the Formula One United States Grand Prix, which it hosted for twenty consecutive years (1961–1980). In addition, the site has also been home to road racing of nearly every class, including the World Sportscar Championship, Trans-Am, Can-Am, NASCAR Cup Series, the International Motor Sports Association and the IndyCar Series. The facility is currently owned by NASCAR subsidiary International Speedway Corporation.

The course was opened in 1956 to host auto races previously held on public roads in and around the village. The circuit's current layout has more or less been the same since 1971 and is a Mecca of North American road racing and is a popular venue among fans and drivers.
