The 2004 United States Senate election in Idaho took place on November 2, 2004, 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 Republican Senator Mike Crapo ran for and won a second term in office in a landslide, as he was the only voting option besides a write-in campaign.
