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.

The 2022 United States Senate elections were held on November 8, 2022, concurrently with other midterm elections at the federal, state and local levels. Regularly scheduled elections were held for 34 of the 100 seats in the U.S. Senate, the winners of which will serve six-year terms beginning with the 118th United States Congress. Two special elections were held to complete unexpired terms. While pundits considered the Republican Party a slight favorite to gain control of the Senate, Senate Democrats outperformed expectations and expanded the majority they had held since 2021, gaining one seat for a functioning 51–49 majority.
