The 1985 Daytona 500, the 27th running of the event, was held on February 17, 1985, at Daytona International Speedway, in Daytona Beach, Florida.

The race restarted on the last lap after a Neil Bonnett spin out with less than four laps to go; Bonnett got out of his car and was credited for a 10th-place finish. The race saw a number of engine problems, which knocked many of the contenders, including former Daytona 500 winners David Pearson, AJ Foyt, Benny Parsons, Bobby Allison, and two-time defending race winner Cale Yarborough, who was trying to win his third straight Daytona 500 victory.
