The Massachusetts United States Senate election of 1936 coincided with the landslide re-election of Democratic incumbent President Franklin D. Roosevelt over Republican candidate Alf Landon (who won just two states against Roosevelt's 46). The same year Democrats won six United States Senate seats from the Republicans, which gave them one of the largest Senate majorities ever. The Republicans retained just 16 seats. The Massachusetts election was notable because this was the only state in which Republicans won a seat from Democrats in this election.
