The 1956 Montana gubernatorial election took place on November 6, 1956. Incumbent governor of Montana J. Hugo Aronson, who was first elected Governor in 1952, ran for re-election. He was unopposed in the Republican primary and advanced to the general election, where he faced Arnold Olsen, the Attorney General of Montana and the Democratic nominee. Despite the fact that then-President Dwight D. Eisenhower won the state in a landslide that year in the presidential election, Aronson only narrowly defeated Arnold to win his second and final term as governor.
