The 1994 First Union 400 was the seventh stock car race of the 1994 NASCAR Winston Cup Series season and the 44th iteration of the event.

In a late-race charge, Hendrick Motorsports driver Terry Labonte would make a pass for the lead with 30 to go and hold off the field to take his 12th career NASCAR Winston Cup Series victory, his first victory of the season, and his first win in 135 races, having not won since the 1989 Talladega DieHard 500.

It measures 0.625 mi (1.006 km) and features a unique uphill backstretch and downhill frontstretch.

The speedway briefly reopened in 2010 and hosted several stock car series races before closing again in the spring of 2011.

Ernie Irvan, driving for Robert Yates Racing, would win the pole, setting a time of 18.905 and an average speed of 119.016 miles per hour (191.538 km/h) in the first round.
