The 2015 NASCAR Whelen Modified Tour was the thirty-first season of the Whelen Modified Tour (WMT). It began with the Icebreaker 150 at Thompson Speedway Motorsports Park on April 12 and concluded at the same venue with the Sunoco World Series 150 on October 18.
Defending champion Doug Coby won his third series title, and as a result, became the first driver since Tony Hirschman, Jr. to win successive Whelen Modified Tour championships. Coby was the season's most prolific winner – with seven victories – including the final three races which allowed him to overhaul Ryan Preece in the standings, with Coby ultimately prevailing by eleven points after entering the final race tied on points with Preece. Preece was a four-time race winner, and finished all but one race inside the top-ten placings. Just like Preece, Woody Pitkat recorded fourteen top-ten finishes out of fifteen starts – winning at Stafford along with the non-championship Shootout at New Hampshire – as he finished third in points, two down on Preece and thirteen behind Coby. The only other drivers to win races during the season were Todd Szegedy at New Hampshire and Justin Bonsignore, who swept both races at his local track, Riverhead Raceway.
