The 1948 United States Senate election in Minnesota took place on November 2, 1948. It was the first election held for Minnesota's Class 2 seat in the United States Senate since the Minnesota Democratic Party and the Farmer-Labor Party of Minnesota merged in 1944 to form the Minnesota Democratic-Farmer-Labor Party. Democratic Mayor of Minneapolis and future Vice President Hubert H. Humphrey defeated incumbent Republican Joseph H. Ball, who sought a third term in the Senate. This is the first time a Democrat won a Senate seat in Minnesota through popular vote election.
