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.

The 1956 United States presidential election was the 43rd quadrennial presidential election. It was held on Tuesday, November 6, 1956. Incumbent Republican President Dwight D. Eisenhower and his running mate, incumbent Vice President Richard Nixon, were re-elected, defeating for a second time Democrat Adlai Stevenson II, former Illinois governor. This election was the sixth rematch in American presidential history, a situation which would not occur again until 2024. It was the second time in which the winner was the same both times, the first being William McKinley's victories over William Jennings Bryan in 1896 and 1900. This was the last election before term limits established by the 22nd Amendment, which applied to Eisenhower, were effective.
