Michael Stefanik (May 20, 1958 – September 15, 2019) 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 (two in the Busch North Series) tie him with Richie Evans for most in NASCAR history.
According to Connecticut State Police, on the afternoon of September 15, 2019, Stefanik took off in a friend's Aero-Works Aerolite 103 from Riconn Airport (Greene, Rhode Island), and was headed back when it experienced mechanical problems causing it to lose power and crash in a wooded area in Sterling, Connecticut. He was airlifted to Rhode Island Hospital, where he died from his injuries.
