The United States Senate election in Washington of 1952 was held on November 4, 1952. Incumbent and highly-controversial Republican Harry Cain ran for a second term in office, but was defeated by Democratic U.S. Representative Henry M. Jackson. Jackson would come to serve 30 years as a United States Senator, and this would be his only election to the Senate in which he lost any of the state's counties.
