The 1989 Miller High Life 400 was the 22nd stock car race of the 1989 NASCAR Winston Cup Series season and the 32nd iteration of the event.

Gambling on fuel strategy, Blue Max Racing driver Rusty Wallace would manage to run the last 129 laps of the race on one tank of fuel to take his 16th career NASCAR Winston Cup Series victory and his sixth and final victory of the season.

The first round was held on Thursday, September 8, 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.

Bill Elliott, driving for Melling Racing, would win the pole, setting a time of 22.289 and an average speed of 121.136 miles per hour (194.949 km/h) in the first round.
