The 2006 United States House of Representatives elections in Connecticut were held on November 7, 2006, to elect the five members of the U.S. House, one from each of the state's congressional districts, to represent Connecticut in the 110th Congress. The elections coincided with a state gubernatorial election and a U.S. Senate election, as well as with Congressional elections in other states.
