The 1993 Pepsi 400 was the 15th stock car race of the 1993 NASCAR Winston Cup Series season and the 35th iteration of the event.

At race's end, Richard Childress Racing driver Dale Earnhardt would manage to fend off the field on the final restart with nine to go to take his 57th career NASCAR Winston Cup Series victory and his fourth victory of the season.

The standard track at Daytona International Speedway is a four-turn superspeedway that is 2.5 miles (4.0 km) long.

For this specific race, positions 21-40 would be decided on time,[3] and 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 provisionals were given.

Ernie Irvan, driving for Morgan–McClure Motorsports, would win the pole, setting a time of 47.287 and an average speed of 190.327 miles per hour (306.302 km/h) in the first round.
