The 1993 Miller Genuine Draft 400 was the 14th stock car race of the 1993 NASCAR Winston Cup Series season and the 25th iteration of the event. The race was held on Sunday, June 20, 1993, in Brooklyn, Michigan, at Michigan International Speedway, a two-mile (3.2 km) moderate-banked D-shaped speedway. The race took the scheduled 200 laps to complete. In the final laps of the race, Hendrick Motorsports driver Ricky Rudd would manage to take advantage of a fuel-stricken Mark Martin, coasting his car to the finish on fuel to take his 14th career NASCAR Winston Cup Series victory and his only victory of the season.^[1][2] To fill out the top three, Hendrick Motorsports driver Jeff Gordon and Morgan–McClure Motorsports driver Ernie Irvan would finish second and third, respectively.

The race was held at Michigan International Speedway, a two-mile (3.2 km) moderate-banked D-shaped speedway located in Brooklyn, Michigan. The track is used primarily for NASCAR events. It is known as a "sister track" to Texas World Speedway as MIS's oval design was a direct basis of TWS, with moderate modifications to the banking in the corners, and was used as the basis of Auto Club Speedway. The track is owned by International Speedway Corporation. Michigan International Speedway is recognized as one of motorsports' premier facilities because of its wide racing surface and high banking (by open-wheel standards; the 18-degree banking is modest by stock car standards).

Qualifying was split into two rounds. The first round was held on Friday, June 18, at 3:30 PM EST. Each driver would have one lap to set a time. During the first round, the top 20 drivers in the round would be guaranteed a starting spot in the race. If a driver was not able to guarantee a spot in the first round, they had the option to scrub their time from the first round and try and run a faster lap time in a second round qualifying run, held on Saturday, June 19, at 11:00 AM EST. As with the first round, each driver would have one lap to set a time. 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. If needed, a past champion who did not qualify on either time or provisionals could use a champion's provisional, adding one more spot to the field.

Brett Bodine, driving for King Racing, would win the pole, setting a time of 41.036 and an average speed of 175.456 miles per hour (282.369 km/h) in the first round.^[4]

Two drivers would fail to qualify.
