The 1990 Miller Genuine Draft 400 was the 22nd stock car race of the 1990 NASCAR Winston Cup Series season and the 33rd iteration of the event.

Gambling on fuel strategy, Richard Childress Racing driver Dale Earnhardt would manage to defend the field in a final three-lap restart to the finish to take his 47th career NASCAR Winston Cup Series victory and his eighth victory of the season.

The first round was held on Friday, September 7, at 3:00 PM EST.

For this specific race, positions 21-34 would be decided on time,[5] 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 were given.

Ernie Irvan, driving for Morgan–McClure Motorsports, would win the pole, setting a time of 22.524 and an average speed of 119.872 miles per hour (192.915 km/h) in the first round.
