The Pop Secret Microwave Popcorn 400 was a NASCAR Winston Cup Series event that took place in November at the North Carolina Motor Speedway from 1965 to 2003. It was the first NASCAR Cup Series victory for three drivers including Mark Martin in 1989, Ward Burton in 1995, and Johnny Benson in 2002. It was the final race win for Bill Elliott in 2003.

This race, typically run as the penultimate race of the NASCAR season, was dropped from the schedule after the 2003 season. The Pop Secret sponsorship was moved over to the newly acquired Labor Day date at Auto Club Speedway, while the late season date was originally taken over by the Southern 500 at Darlington and later the fall race at Texas, which was moved to Spring in 2024 after the track dropped its original spring race in 2021.
