The 1962 United States Senate elections was an election for the United States Senate. Held on November 6, the 34 seats of Class 3 were contested in regular elections. Special elections were also held to fill vacancies. They occurred in the middle of President John F. Kennedy's term. His Democratic Party made a net gain of four seats from the Republicans, increasing their control of the Senate to 68–32. However, this was reduced to 67–33 between the election and the next Congress, as on November 18, 1962, Democrat Dennis Chávez, who was not up for election that year, died. He was replaced on November 30, 1962, by Republican appointee Edwin L. Mechem. Additionally, Democrat Strom Thurmond became a Republican in 1964, further reducing Democrats to 66–34. This was the first time since 1932 that Democrats gained seats in this class of Senators.

This was the first time since 1914 that the president's party gained seats in the Senate and lost seats in the House, this would occur again in 1970, 2018, and 2022. This was the last time until 2022 that the Democrats would win full terms in Arizona's and Pennsylvania's Class 3 Senate seats.
