The 1916 Montana gubernatorial election took place on November 7, 1916. Incumbent Governor of Montana Sam V. Stewart, who was first elected governor in 1912, ran for re-election. After comfortably winning the Democratic primary, he advanced to the general election, where he faced Frank J. Edwards, the former Mayor of Helena, who narrowly emerged victorious in a close Republican primary. Benefitting from then-President Woodrow Wilson's landslide victory in Montana in the presidential election that year, Stewart narrowly won re-election to his second and final term as governor.
