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.

Samuel Vernon Stewart was an American attorney and Democratic Party politician, an attorney, former Montana Supreme Court Justice and the sixth Governor of Montana.
