The 1960 United States Senate election in Montana took place on November 8, 1960. 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, and
1954, declined to seek re-election, creating an open seat. United States Congressman
Lee Metcalf won out in a crowded
Democratic primary and faced off against former United States Congressman
Orvin B. Fjare, who won in a similarly-crowded
Republican primary. Following a close general election, Metcalf narrowly defeated Fjare to win his first term in the Senate.
