The 1948 United States Senate election in Montana took place on November 2, 1948. 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 and 1942, ran for re-election. After winning the Democratic primary, he faced Tom J. Davis, an attorney and the Republican nominee, in the general election. Following a narrow re-election in 1936, Murray significantly expanded his margin of victory and comfortably won re-election over Davis, resulting in him winning his fourth term and his third full term in the Senate.
