The Pop Secret Microwave Popcorn 400 was a NASCAR Winston Cup 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.

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 California Speedway, while the late season date was originally taken over by the Southern 500 at Darlington and is now occupied by the Dickies 500 at Texas.
