The 1973 United States Grand Prix was a Formula One motor race held on October 7, 1973 at the Watkins Glen Grand Prix Race Course in Watkins Glen, New York. It was race 15 of 15 in 1973 Formula One season.
The race was won from pole position by Ronnie Peterson, driving a Lotus-Ford. Peterson held off James Hunt in the Hesketh-entered March-Ford to take his fourth victory of the season, with Carlos Reutemann third in a Brabham-Ford.
The race was overshadowed by the death of François Cevert during qualifying, the day before, in what was to have been the 100th and final Grand Prix for Tyrrell team-mate and triple World Champion Jackie Stewart. The Tyrrell team withdrew from the event as a consequence, handing the Manufacturers' Cup to Lotus.
