The United States House of Representatives elections in Idaho occurred on November 8, 2016. The state chose two individuals to represent Idaho in the U.S. House. Idaho's voting system is a mixed primary system. The Democratic Party permits unaffiliated voters to vote in the primary. The Republican Party grants registered voters the right to vote. Non-affiliated electors can choose to ally with a party on election day, however, they will be obligated to that party at the next election. The primaries were held on May 17.
