Since becoming a U.S. state in 1959, Alaska has been entitled to one member in the United States House of Representatives, elected in the state's sole, at-large congressional district. By area, Alaska's congressional district is the largest congressional district in the United States and the third-largest electoral district represented by a single member in the world, behind only Yakutsk district in Russia and Nunavut's sole electoral district in Canada.

The United States House of Representatives is the lower chamber of the United States Congress, with the Senate being the upper chamber. Together, they comprise the national bicameral legislature of the United States. The House is charged with the passage of federal legislation, known as bills; those that are also passed by the Senate are sent to the president for signature or veto. The House's exclusive powers include initiating all revenue bills, impeaching federal officers, and electing the president if no candidate receives a majority of votes in the Electoral College.
