The 1936 United States Senate election in Maine was held on September 14, 1936. Incumbent Republican U.S. Senator Wallace White was re-elected to a second term over Governor Louis J. Brann.
Although 1936 is typically seen as the end of Maine's status as a national bellwether, White's narrow victory in strongly Republican Maine may have been a portent of doom for Alf Landon's fall presidential campaign, in which he carried only Maine and nearby Vermont. Brann himself had overcome the state's Republican lean to win his two terms as governor.
Senator White was unopposed for re-nomination.
Governor Brann was unopposed for the Democratic nomination.
