The 1993 Motorcraft Quality Parts 500 was the fourth stock car race of the 1993 NASCAR Winston Cup Series season and the 34th iteration of the event.

The race was originally scheduled to be held on Sunday, March 14, 1993, but was postponed by nearly a week due to the 1993 Storm of the Century that affected a majority of the American East Coast.

Depending on fuel mileage, Wood Brothers Racing driver Morgan Shepherd would manage to conserve enough fuel on the final green flag stint to take his fourth and final career NASCAR Winston Cup Series victory and his only victory of the season.

*Driver switched to Greg Sacks for the race due to Jones having prior commitments in the IMSA GT Championship.

[5] Rusty Wallace, driving for Penske Racing South, would win the pole, setting a time of 30.653 and an average speed of 178.749 miles per hour (287.669 km/h) in the first round.
