The 1952 United States Senate election in Mississippi took place on November 4, 1952. Incumbent Democratic U.S. Senator John C. Stennis was re-elected to his second (his first full) term in office.
Because Stennis was unopposed in the general election, his victory in the August 26 primary was tantamount to election. He defeated William P. Davis in a landslide.
The Democratic primary election was held on August 26, 1952.
