The 1991 Bud 500 was the 20th stock car race of the 1991 NASCAR Winston Cup Series and the 32nd iteration of the event.

Despite its short length, Bristol is among the most popular tracks on the NASCAR schedule because of its distinct features, which include extraordinarily steep banking, an all concrete surface, two pit roads, and stadium-like seating.

Bill Elliott, driving for Melling Racing, would win the pole, setting a time of 16.406 and an average speed of 116.957 miles per hour (188.224 km/h) in the first round.
