The 2012 NASCAR Whelen Southern Modified Tour was the eighth season of the NASCARWhelen Southern Modified Tour (WSMT). It began with the Spring Classic 150 at Caraway Speedway on March 31. It ended with the UNOH Southern Slam 150 at Charlotte Motor Speedway on October 11. George Brunnhoelzl III, who entered the season as the defending Drivers' Champion, would win his third championship in the series, fifty-three points ahead of series runner up Danny Bohn.
^The UNOH Perfect Storm 150 was held as a combined event, with competitors from the Whelen Southern Modified Tour competing along with competitors for the Whelen Modified Tour. The race was run with a series-based point distribution, where drivers received points and statistical credit for their finish relative to other drivers in their series, not to the whole field in general.
