A general election was held in the U.S. state of Idaho on November 2, 2010. All of Idaho's executive offices were up for election, as well as a United States Senate seat and Idaho's two seats in the United States House of Representatives. Primary elections were held on May 25, 2010.

Idaho has two representatives in the United States House of Representatives. While incumbent Republican Mike Simpson comfortably won re-election, Democrat Walt Minnick was seen as one of the most vulnerable incumbents heading into election day as he worked to build a moderate profile. Republican state representative Raúl Labrador won the Republican primary and eventually defeated Minnick, flipping his district.
Incumbent Republican governor Butch Otter won re-election, defeating Democrat Keith Allred.
Republican Brad Little was appointed to the office of lieutenant governor by Butch Otter in 2009 to fill the vacancy left by Jim Risch following his election to the United States Senate in 2008.
