2004 Kentucky House of Representatives election

The 2004 Kentucky House of Representatives elections were held on November 2, 2004, as part of the biennial United States elections. All 100 of Kentucky's state representatives were up for reelection. In Kentucky, members of the House of Representatives serve two-year terms. Accordingly, they are up for reelection in both presidential and midterm election years.

Democrats held onto their majority in the House, which had been in democratic control since the 1921 elections. They continued to be the majority party in the House until the 2016 election. Despite keeping their majority, Democrats lost seven seats to Republicans in the Jackson Purchase and Pennyroyal regions.
