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.
Senator White was unopposed for re-nomination.
Governor Brann was unopposed for the Democratic nomination.
