Donald Scott Pruett (born March 24, 1960 in Sacramento, California) is an American race car driver who has competed in NASCAR, Champ Car, IMSA, Trans-Am and Grand-Am. He and his wife Judy are children's book authors.

Pruett started racing go karts at the age of eight and went on to win ten professional karting championships. In the 80's, he established himself as a top American sports car racer, eventually winning two IMSA GTO Championships and three Trans Am Championships.

In the 1990s, Pruett was a regular in the CART (now Champ Car) series. From 1988 to 1999, he made 145 starts with two wins, five poles, and fifteen podiums (top three finishes). In preseason testing in 1990, Pruett was involved in a serious crash at West Palm Beach, Florida, where he seriously injured both legs. Pruett sat out the entire 1990 season in order to recover.

Following his Champ Car career, Pruett raced a full season in the NASCAR Winston Cup Series in 2000 with PPI Motorsports, with little success. He then moved back to sports car racing, winning his third Trans-Am championship in 2003. Since 2004, he has raced in the Grand-AmRolex Sports Car Series for Chip Ganassi Racing. Pruett is still a regular starter at NASCAR road course races, and is often referred to as a Road Course Ringer.

Pruett also worked for several years as a commentator for Champ Car races on Speed Channel.

*In a very controversial finish, Pruett was leading late in the race in the Nascar Busch Series in the Telcel-Motorola 200 where he started on the pole, when his very own teammate, Juan Pablo Montoya, spun him out with ample laps to go. Up until that point Pruett had led a number of laps but Montoya had been closing in even after a fuel problem forced him pit an extra time. He was quoted of saying of his only teammate after the race "Now that is no good, low-down, dirty racing right there". The owner of the two cars, Chip Ganassi said sometime before the incident that he just asked that they do not wreck each other out. The win officially marked the first of Juan Pablo Montoya's Nascar career. *Won overall race and Daytona Prototype in the Rolex 24 at Daytona, with Juan Pablo Montoya, and Salvador Duran in the #01 Telmex, Target, Lexus Riley, for Chip Ganassi Racing. *Won the pole for the Telcel-Motorola 200 at Autodromo Hermanos Rodriguez.
