The 1970 United States Senate election in Montana took place on November 3, 1970. Incumbent United States Senator Mike Mansfield, who was first elected to the Senate in 1952 and was re-elected in 1958 and 1964, ran for re-election. Mansfield won the Democratic primary against several opponents, and advanced to the general election, where he was opposed by Harold E. Wallace, a sporting goods salesman and the Republican nominee. While his margin of victory decreased slightly from 1964, Mansfield still managed to defeat Wallace in a landslide, winning his fourth and final term in the Senate.
