The NASCAR Craftsman Truck Series is a popular NASCAR racing series that features modified pickup trucks. It is one of the three national divisions of NASCAR, together with the Busch Series and the Nextel Cup.

The NASCAR Craftsman Truck Series was formed in 1994. In 1994 NASCAR announced the formation of the NASCAR SuperTruck Series presented by Craftsman, with the first series race in 1995. In 1996 it was renamed the NASCAR Craftsman Truck Series because of Craftsman's involvement.

The series distinguishes itself from the two other top series in NASCAR by using a heavily modified version of a pickup truck instead of a car. The series was first considered something of an oddity or a "senior's tour" for NASCAR drivers, but eventually grew in popularity and has produced Nextel Cup series drivers who had never raced in the Busch Series.
