The 1948 United States presidential election in Louisiana took place on November 2, 1948, as part of the 1948 United States presidential election. State voters chose ten representatives, or electors, to the Electoral College, who voted for president and vice president.
Louisiana was won by Governor Strom Thurmond (DX–South Carolina), running with Governor Fielding L. Wright, with 49.07% of the popular vote, against incumbent President Harry S. Truman (D–Missouri), running with Senator Alben W. Barkley, with 32.75% of the popular vote, and Governor Thomas E. Dewey (R–New York), running with Governor Earl Warren, with 17.45% of the popular vote.
This marked the first time since 1876 that Louisiana failed to back the Democratic nominee in a presidential election, and the first time ever that a Democrat won the presidency without carrying the state.
52% of white voters supported Thurmond.
