During the 2004 United States elections, there was controversy around various aspects of the voting process, including whether voting had been made accessible to all those entitled to vote, whether ineligible voters were registered, whether voters were registered multiple times, and whether the votes cast had been correctly counted.

There was generally less attention paid to the Senate and House elections and to various state races, but some of them were also questioned, especially the gubernatorial election in Washington, which was decided by less than 0.01% and involved several recounts and lawsuits. The final recount also reversed the outcome of this election.
