Arnold Olsen (December 17, 1916 – October 9, 1990) was a U.S. Democratic politician who served as the Attorney General of Montana from 1949 to 1957, and as a member of the United States House of Representatives from Montana's 1st congressional district from 1961 to 1971.
He was born in Butte, Montana on December 17, 1916. He attended Butte public schools, the Montana School of Mines, 1934–1936, and graduated from the Montana State University Law School (now the University of Montana), Missoula, Montana in 1940. He served four years of overseas duty in the Navy during World War II. Upon returning to the States, Olsen married Mary Margaret Williams, of Butte. They had three children - Margaret Rae Olsen, Anna Kristine Olsen, and Karin Synneve Olsen Billings. Arnold and Margaret have 5 grandchildren; John David Childs, Todd Arnold Graetz, Kara Ann (Graetz) Trapp; Jonathan Olsen Billings and Luke Alexander Billings.
Olsen opened a private law practice in 1940. He was elected as Attorney General of Montana in 1948, and was re-elected in 1952. Rather than seek re-election, he instead opted to run for Governor of Montana in 1956, and, after narrowly defeating former Governor John W. Bonner in the Democratic primary, advanced to the general election, where he faced incumbent Governor J. Hugo Aronson. Following a close campaign, Olsen narrowly lost to Aronson. Following his defeat, he ran for the position of Chief Justice of the Montana Supreme Court, but lost to incumbent Chief Justice James T. Harrison by a slim margin.
In 1960, when Congressman Lee Metcalf opted to run for the Senate rather than seek re-election, Olsen ran to succeed him in the 1st congressional district. He defeated George P. Sarsfield, the Republican nominee, winning his first of five terms. Olsen was narrowly re-elected over Republican Wayne Montgomery in 1962, and by a wider margin against Montgomery in 1964. In 1966, he defeated Republican nominee Dick Smiley by about two thousand votes, and, in a rematch against Smiley in 1968, by a wider margin. When Olsen ran for a sixth term in 1970, he was narrowly defeated for re-election by Richard G. Shoup, the Mayor of Missoula. He ran against Shoup again in 1972, but ultimately lost to him. In 1974, he ran for Congress one final time, but lost in the Democratic primary to Max Baucus, who ended up defeating Shoup in the general election.
Following his final defeat for public office, Olsen was appointed by Governor Thomas Lee Judge to the Second Judicial District of Montana, where he served until his death in 1990.
