1956 United States presidential election in Montana

The 1956 United States presidential election in Montana took place on November 6, 1956 as part of the 1956 United States presidential election. Voters chose four representatives, or electors to the Electoral College, who voted for president and vice president.

Montana strongly voted for the Republican nominee, President Dwight D. Eisenhower, over the Democratic nominee, former Illinois Governor Adlai Stevenson. Eisenhower won Montana by 14.26%; however, owing to a five-year drought in the High Plains that resulted in a considerable protest vote for Stevenson, he did not do as well as had four years earlier.

However, his strong Catholic appeal meant that Eisenhower gained substantially in the heavily Irish mining counties of the west. His 48.61% in Deer Lodge County is the best by a Republican there since Warren G. Harding in 1920, and as of the 2020 presidential election, this is the only election since 1920 in which Silver Bow County voted for a Republican Presidential candidate. In addition to that, this is the only election since 1924, as of 2020, in which neighboring Deer Lodge and Silver Bow counties voted for different candidates, the two normally being Democratic strongholds.
