The 1994 Mountain Dew Southern 500 was the 23rd stock car race of the 1994 NASCAR Winston Cup Series season and the 45th iteration of the event.

In the final stages of the race, Junior Johnson & Associates driver Bill Elliott would make a late-race charge to the lead, passing with 13 to go to take his 40th career NASCAR Winston Cup Series victory and his only victory of the season.

It is of a unique, somewhat egg-shaped design, an oval with the ends of very different configurations, a condition which supposedly arose from the proximity of one end of the track to a minnow pond the owner refused to relocate.

This situation makes it very challenging for the crews to set up their cars' handling in a way that is effective at both ends.

Geoff Bodine, driving for his own Geoff Bodine Racing team, would win the pole, setting a time of 29.447 and an average speed of 166.998 miles per hour (268.757 km/h) in the first round.
