The 2005 United States elections were held on Tuesday, November 8. During this off-year election, the only seats up for election in the United States Congress were special elections held throughout the year. None of these congressional seats changed party hands. There were also two gubernatorial races, state legislative elections in two states, numerous citizen initiatives, mayoral races in several major cities, and a variety of local offices on the ballot.
