The 1944 United States Senate election in Louisiana was held on November 7, 1944. Incumbent Democrat Senator John H. Overton was elected to a third term in office.
On September 12, Overton won the Democratic primary with 61.64% of the vote.
At this time, Louisiana was a one-party state (no other party had run a candidate for Senate since the passage of the Seventeenth Amendment), and the Democratic nomination was tantamount to victory. Overton won the November general election without an opponent.
