The 2004 United States House of Representatives election in Wyoming was held on November 2, 2004. Incumbent Republican Congresswoman Barbara Cubin ran for re-election to a sixth term. Cubin faced several challengers in the Republican primary, several of whom attacked her for missing votes in Congress. While Cubin won the primary, she received only 55 percent of the vote. In the general election, she was opposed by Ted Ladd, the Democratic nominee and a business consultant. While Cubin won re-election overwhelmingly, she won by a significantly narrower margin than President George W. Bush did in the presidential election, and lost two counties (Albany and Laramie) that Bush carried.
