The 1946 United States Senate election in Wisconsin was held on November 5, 1946.

Incumbent Republican U.S. Senator Robert La Follette, Jr. (who had until 1946 been a member of the Progressive Party) narrowly lost the primary election to Joseph McCarthy. McCarthy would go on to win the general election against Rep. Howard McMurray of Milwaukee in a landslide. McCarthy became the first person other than a La Follette to hold this seat since 1906.
