The 1940 United States presidential election in Montana took place on November 5, 1940, as part of the 1940 United States presidential election. Voters chose four representatives, or electors to the Electoral College, who voted for president and vice president.
Montana voted powerfully to give Democratic nominee, President Franklin D. Roosevelt an unprecedented third term, over the Republican nominee, corporate lawyer Wendell Willkie, a dark horse candidate that had never before run for a political office. Roosevelt won Montana by a convincing 18.61% margin. As of the 2020 presidential election, this remains the last election in which the following counties have voted for a Democratic presidential nominee: Broadwater, Madison, Meagher and Garfield.
