The 1954 United States Senate election in Montana took place on November 2, 1954. Incumbent United States Senator
James E. Murray, who was first elected to the Senate in a special election in
1934 and was re-elected in
1936,
1942, and
1948, ran for re-election. After winning the
Democratic primary against trivial opponents, he advanced to the general election, where he was opposed by
Wesley A. D'Ewart, the
Republican nominee and the
United States Congressman from
Montana's 2nd congressional district. A contentious and close election ensued, but ultimately, Murray was able to narrowly win re-election over D'Ewart to a final term in the Senate.
