The 1991 Hanes 500 was the eighth stock car race of the 1991 NASCAR Winston Cup Series and the 42nd iteration of the event.

With the assist of a late caution, on the final restart with 38 laps to go in the race, Richard Childress Racing driver Dale Earnhardt would manage to mount a late-race charge to the lead on the ensuing restart to take his 50th career NASCAR Winston Cup Series victory and his second victory of the season.

[1][2][3] To fill out the top three, SABCO Racing driver Kyle Petty and owner-driver Darrell Waltrip would finish second and third, respectively.

Depending on who needed it, a select amount of positions were given to cars who had not otherwise qualified but were high enough in owner's points; up to two were given.

[5] Mark Martin, driving for Roush Racing, would win the pole, setting a time of 20.594 and an average speed of 91.949 miles per hour (147.978 km/h).
