2020 United States Senate election in Idaho

The 2020 United States Senate election in Idaho was held on November 3, 2020, to elect a member of the United States Senate to represent the State of Idaho, concurrently with the 2020 U.S. presidential election, as well as other elections to the United States Senate, elections to the United States House of Representatives and various state and local elections.

Incumbent Republican senator Jim Risch won reelection to a third term in office, defeating Democratic nominee Paulette Jordan, who, percentage wise, had the worst performance of a Democratic senatorial candidate for this seat since 2002. However, Risch also performed nearly three points worse than he did when he was reelected in 2014, and he slightly underperformed incumbent president Donald Trump's performance in the concurrent presidential election.
