The 1989 AC Delco 500 was the 27th stock car race of the 1989 NASCAR Winston Cup Series season and the 25th iteration of the event.

The race was held on Sunday, October 22, 1989, before an audience of 52,500 in Rockingham, North Carolina, at North Carolina Speedway, a 1.017 miles (1.637 km) permanent high-banked racetrack.

North Carolina Motor Speedway was opened as a flat, one-mile oval on October 31, 1965.

In 1969, the track was extensively reconfigured to a high-banked, D-shaped oval just over one mile in length.

Alan Kulwicki, driving for his own AK Racing team, would win the pole, setting a time of 24.634 and an average speed of 148.624 miles per hour (239.187 km/h) in the first round.
