The First Union 400 was a former NASCAR Winston Cup race held at North Wilkesboro Speedway in North Wilkesboro, North Carolina, USA, in late March or early April from 1951 to 1996. The race was discontinued when North Wilkesboro lost both of its Cup dates to other tracks and was closed after the annual fall race, the Tyson Holly Farms 400.
