The 2017 NASCAR Whelen Modified Tour will be the thirty-third season of the Whelen Modified Tour (WMT), a tour sanctioned by NASCAR. It will begin with the Performance Plus 150 presented by Safety-Kleen at Myrtle Beach Speedway on March 18 and concludes Sunoco World Series 150 at Thompson Speedway Motorsports Park on October 15. Doug Coby will enter the season as the defending Drivers' Champion. 2017 marks the first season of the unification of the Whelen (Northern) Modified Tour and the Whelen Southern Modified Tour. Timmy Solomito leads the championship after four races, nine points in front of Rowan Pennink.
The All-Star Shootout and the race at Charlotte Motor Speedway do not count towards the championship. The Performance Plus 150 presented by Safety-Kleen and the Icebreaker 150 were shown live on FansChoice.tv. Eleven of the eighteen races in the 2017 season were televised on NBCSN and were on a tape delay basis.
