The 1962 United States Senate election in Connecticut was held on November 6, 1962.
Incumbent Senator Prescott Bush retired instead of seeking a second full term in office. 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.
Congressman Horace Seely-Brown Jr. won an upset victory over former Governor John Davis Lodge at the Republican state convention. After two weeks of deliberation, Lodge opted not to seek a primary challenge and Seely-Brown was unopposed for the Republican nomination on the primary ballot.
Kowalski fell short of the 190 delegates needed to be eligible for a primary election. Ribicoff was unopposed on the primary ballot.
