The U.S. Senate election, 1952 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 Republicans managed to make a net gain of two seats, which was reduced to one when Wayne L. Morse (R-OR) became an independent after his pro-New Deal positions and support for Adlai Stevenson alienated Republican leaders.

Republicans defeated incumbents Ernest W. McFarland (D-AZ and the Majority Leader), William Benton (D-CT), Thomas R. Underwood (D-KY), Blair Moody (D-MI), and Joseph C. O'Mahoney (D-WY), as well as taking the open seat in Maryland. Democrats defeated incumbents Henry Cabot Lodge, Jr. (R-MA), James P. Kem (R-MO), Zales N. Ecton (R-MT), and Harry P. Cain (R-WA).
