1952 United States Senate elections

The 1952 United States Senate elections was an election for the United States Senate which coincided with the election of Dwight D. Eisenhower to the presidency by a large margin. The 32 Senate seats of Class 1 were contested in regular elections, and three special elections were held to fill vacancies. The Republicans took control of the Senate by managing to make a net gain of two seats. However, Wayne Morse (R-OR) became an independent forcing Republicans to rely on Vice President Richard Nixon's tie-breaking vote, although Republicans maintained a 48–47–1 plurality. Throughout the next Congress, Republicans were able to restore their 49–46–1 majority. This was the third time, as well as second consecutive, in which a sitting Senate leader lost his seat.

The 1952 United States Senate elections marked a significant shift in power, with the Republicans gaining control of the Senate by making a net gain of two seats.

This was the last time the Senate changed hands in a presidential election year until 1980 and the last time the Republicans won control of the Senate until 1980. As of 2020, this is the last time both houses simultaneously changed hands in a presidential year.
