The 1999 MBNA Platinum 400 was the 13th stock car race of the 1999 NASCAR Winston Cup Series season and the 31st iteration of the event. The race was held on Sunday, June 6, 1999, in Dover, Delaware at Dover International Speedway, a 1-mile (1.6 km) permanent oval-shaped racetrack. The race took the scheduled 400 laps to complete. Depending on fuel mileage, Joe Gibbs Racing driver Bobby Labonte would manage to save enough fuel to almost lap the field to win his eighth career NASCAR Winston Cup Series victory and his first of the season. To fill out the podium, Hendrick Motorsports driver Jeff Gordon and Roush Racing driver Mark Martin would finish second and third, respectively.
