The 1971 United States Grand Prix was a Formula One motor race held on October 3, 1971, at the Watkins Glen Grand Prix Race Course in Watkins Glen, New York. It was race 11 of 11 in both the 1971 World Championship of Drivers and the 1971 International Cup for Formula One Manufacturers. The 59-lap race was won by Tyrrell driver François Cevert after he started from fifth position. Jo Siffert finished second for the BRM team and March driver Ronnie Peterson came in third.

The two drivers qualified, Andretti in a Ferrari and Donohue in a McLaren shared with David Hobbs, hoping for more rain in New Jersey and the chance to return for the race on Sunday.Since the previous year's race, the course had been resurfaced, widened and, most significantly, lengthened by a mile to 3.377 miles with an entirely new section at the southwest corner called the "Boot" or "Anvil". The pits were also moved from the north end straight back before the right angle turn known as "The 90," which now became Turn One. Friday was sunny and hot (), and Stewart jumped immediately to the top of the charts with a time of 1:42.844, as the times were recorded to a thousandth of a second for the first time.
