The 1936 United States Senate election in Massachusetts was held on November 3. Incumbent Democratic Senator Marcus A. Coolidge declined to stand for re-election. Republican Henry Cabot Lodge Jr. won the race to succeed him over Democratic Boston mayor James Michael Curley and former Suffolk County prosecutor Thomas C. O'Brien.

The election was notable because although Democrats expanded their overall Senate majority to 74 seats, Massachusetts was the only seat gained by Republicans. Curley's campaign may have been damaged by President Roosevelt's decision to remain aloof and the candidacy of O'Brien, who siphoned many usually Democratic Irish-American votes in Boston.
