The 1962 United States Senate election in Connecticut was held on November 6, 1962.

Former Governor of Connecticut and United States Secretary of Health, Education, and Welfare Abraham Ribicoff was elected his successor over Congressman Horace Seely-Brown Jr. Ribicoff had previously sought election to this seat in 1952 but lost to Bush.
