The 2004 United States House of Representatives elections were held on November 2, 2004, to elect all 435 seats of the chamber. It coincided with the re-election of President George W. Bush as well as many Senate elections and gubernatorial elections. Prior to the election in the 108th Congress, Republicans held 227 seats, Democrats held 205, with two Republican vacancies and one independent. As a result of this election, the 109th Congress began composed of 232 Republicans, 201 Democrats, one independent (who caucuses with the Democrats), and one vacancy (Democrat Bob Matsui won reelection, but died just two days before the beginning of the 109th Congress.).

Democrats won open seats in Colorado, South Dakota, and New York while ousting incumbents in Georgia and Illinois. Republicans won an open seat in Kentucky while ousting an incumbent in Indiana. They gained five seats in Texas after a controversial mid-decade redistricting placed several rural Democratic incumbents into new districts. Two seats in Louisiana swapped party control.

As of 2022^[update], this is the last election in which someone who was not from the Democratic or Republican party was elected to the House (Independent Bernie Sanders). Republicans would not make consecutive net gains in the House (after gaining seats in the 2002 election) until 2020 and 2022. This was also the last election in which the Republicans made any gains in a Presidential election year until 2020.
