The 2001 United States Grand Prix (formally the 2001 SAP United States Grand Prix) was a Formula One motor race held on September 30, 2001, at Indianapolis Motor Speedway in Speedway, Indiana in the United States.

After a qualifying battle with Schumacher on Saturday and securing a front-row starting position, Häkkinen dug himself a hole on a cool but sunny race day: first, he slid off the track into the guardrail at the end of the infield straight in the morning warm-up, damaging his McLaren's suspension and requiring a heroic job by his crew to get the car ready to race. Three hours later, he learned that his failure to wait for the green light to begin the warm-up session had caused his best qualifying lap to be taken away, dropping him from second to fourth position on the grid. At the start, Juan Pablo Montoya pulled his Williams from third spot around the outside of Michael Schumacher's Ferrari into Turn 1. Side by side through the initial right-hander, the two avoided contact by inches as Schumacher closed the door and seized the advantage into the left-handed Turn 2. It soon became clear, however, that the fastest car on the track was the
