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. Wayne Morse would caucus with the Republicans at the start of Congress’ second session on January 6, 1954 to allow the GOP to remain in control of the Senate.

Most of the seats that Republicans lost had long been held by Democrats, who now returned with an even stronger base in the major cities.
