Bầu cử tổng thống Hoa Kỳ tại Utah năm 1940

The 1940 United States presidential election in Utah took place on November 5, 1940, as part of the 1940 United States presidential election. All contemporary forty-eight states took part, and state voters selected four voters to the Electoral College, who voted for president and vice president.

Utah, like every other state west of the Continental Divide, voted for Franklin D. Roosevelt over Wendell Willkie by a substantial margin. This was the first time any Democrat won the state more than twice. Roosevelt landslided Utah with 62.25 percent of the vote. The percentage, however, wasn't as large as his victory in the state four years earlier. As of the 2024 presidential election, this is the last election in which Piute County voted for a Democratic presidential candidate.
