James Christopher "Jamie" McMurray (born June 3, 1976) is an American professional driver. He is best known for winning the 2002 UAW-GM Quality 500 as a substitute driver for Sterling Marlin in his second Cup start, and is one of only three drivers to win both the Daytona 500 and Brickyard 400 in the same year. He currently competes full-time in the Monster Energy NASCAR Cup Series, driving the No. 1 Chevrolet SS for Chip Ganassi Racing.

In 1999, McMurray made five starts in the Craftsman Truck Series. In 2000, he ran 16 Truck races and posted one top-five and four top-ten finishes. During 2001 and 2002, he competed full-time in the Busch Series; driving the No. 27 Williams Travel Centers Chevrolet Monte Carlo for Brewco Motorsports. The latter year was better for McMurray, as he won two races and finished sixth in the overall points standings.

Before the fall race at Richmond in 2002, Chip Ganassi announced McMurray would become the driver of a Texaco-Havoline Dodge in 2003. Ganassi planned to have McMurray drive the No. 42 Dodge for seven races in 2002.

McMurray's entry into Cup racing did not go as planned. McMurray was scheduled to drive a limited schedule in a No. 42 Chip Ganassi Racing Dodge in 2002, in preparation for a full-time 2003 rookie of the year campaign in the No. 42 with new sponsor Texaco/Havoline. However, he was instead tapped as interim replacement for injured Ganassi Cup driver Sterling Marlin, who fractured a vertebra in a crash at Kansas Speedway. Thus, McMurray made his Cup debut in the No. 40 Coors Light Dodge at Talladega. One week later, at Charlotte, in just his second career NASCAR Winston Cup and first non-restrictor plate start, McMurray outraced the Joe Gibbs Racing Pontiacs of Bobby Labonte and Tony Stewart to win the UAW-GM Quality 500. McMurray had been consistent the entire night, and led 96 of the final 100 laps to score the win. It is considered one of the biggest upsets in NASCAR history. This win set a modern era record for fewest starts before a win (which has since been recently tied by Trevor Bayne in the 2011 Daytona 500, although a difference is that Bayne's win was on a restrictor plate track where upsets are frequent due to the plates equalizing the cars, while Charlotte, where McMurray won, is a track that requires more driver skill), and it was also the first time a driver won in their first start at a 1.5-mile track; the most common type of track used in the sport. McMurray drove for six of the remaining seven races, except for the Old Dominion 500 at Martinsville, with Mike Bliss driving as scheduled in the No. 40.
