The 1924 United States Senate election in Montana took place on November 4, 1924. Incumbent United States Senator Thomas J. Walsh, who was first elected to the Senate in 1912 by the state legislature (as was the practice then), and re-elected in 1918 by popular vote (in accordance with the 17th Amendment), ran for re-election. He was unopposed in the Democratic primary.
He faced former State Representative Frank Bird Linderman and several independent opponents in the general election. Walsh ultimately won re-election to his third term by a solid margin.
