The 1936 United States Senate election in Wyoming was held on November 3, 1936. First-term Republican Senator Robert D. Carey ran for re-election. In a rematch of the 1930 race, he once again faced Harry Schwartz, who had since been elected to the State Senate. Carey's fortunes turned considerably from six years prior; he lost re-election to Schwartz by a decisive margin as President Franklin D. Roosevelt defeated Republican presidential nominee Alf Landon in Wyoming in a landslide.
