Michael Paul Stefanik was an American professional stock car racing driver. He competed mainly in the NASCAR Whelen Modified Tour, but also made appearances in the Busch Grand National series and the Craftsman Truck Series. A seven-time champion in the Modified series, Stefanik was named the second greatest NASCAR Modified driver of all-time in 2003. His nine total championships tie him with Richie Evans for the most in NASCAR history. Stefanik is a member of the 2021 NASCAR Hall of Fame class.

The NASCAR Whelen Modified Tour (NWMT) is a modified stock car racing series owned and operated by NASCAR in the Modified Division. The Modified Division is NASCAR's oldest division, and is the only open-wheeled division that NASCAR sanctions. NASCAR Whelen Modified Tour events are mainly held in the northeastern United States, but the 2007 and 2008 tours expanded to the Midwest with the addition of a race in Mansfield, Ohio. The tour races primarily on short oval paved tracks, but the NWMT also has made appearances at larger ovals and road courses.
