The 1958 United States Senate election in Arizona took place on November 4, 1958. Incumbent Republican U.S. Senator Barry Goldwater ran for reelection to a second term, and defeated former U.S. Senator, and then-Governor, Ernest McFarland in the general election. The election was a rematch from 1952, where Goldwater defeated McFarland by a narrow margin. Goldwater had attributed the 1952 win to the unpopularity of President Harry S. Truman and popular Wisconsin Senator Joseph McCarthy endorsing his campaign.{{cite book|first1=John W.|last1=Dean|last2= Goldwater Jr.|first2= Barry M. |title=Pure Goldwater|year=2008|publisher=Palgrave Macmillan|location=New York|isbn=978-0230611337|url=https://archive.org/details/puregoldwater00gold|url-access=registration|page=[https://archive.org/details/puregoldwater00gold/page/72 72]|quote=1952 mcfarland goldwater.|edition=1st}}

This would be McFarland's final run for statewide office. He became an associate justice of the Arizona Supreme Court in 1965 and Chief Justice in 1968 before retiring from public service.{{cite web |url=http://bioguide.congress.gov/scripts/biodisplay.pl?index=M000438 |title=McFarland, Ernest William, (1894–1984) |publisher=Biographical Directory of the U.S. Congress |access-date=April 29, 2017}}

This election was the first time ever that an incumbent Republican Senator from Arizona was re-elected or won re-election.
