The 1980 United States Senate election in Idaho took place on November 4, 1980, alongside other elections to the United States Senate in other states as well as elections to the United States House of Representatives and various state and local elections. Incumbent Democrat Frank Church ran for a fifth term and narrowly lost to Republican Steve Symms.
This is the last time that a Senator from Idaho lost re-election. Since Symms took office in 1981, Republicans have held both of Idaho's U.S. Senate seats, which they had last done in 1957.
