The 1991 Busch Clash was a Winston Cup (now Sprint Cup) exhibition race for the 1990 pole winners run on February 10 at Daytona International Speedway in Daytona Beach, Florida. Dale Earnhardt dominated en route to his fourth Clash win, starting sixth and leading 18 of 20 laps. Additionally, this year marked the first format change for the Clash. Instead of having a single 20-lap "dash for cash," the race was split into two 10-lap segments separated by a short intermission. The field was also inverted at the start of the second segment, and prize money was awarded for both segments.
