These include the most highly recognized historic sites in Connecticut that are officially designated and/or funded and operated by the U.S. Federal Government.

There are many additional historic sites in Connecticut that are federally recognized by listing on the National Register of Historic Places, but only those NRHP-listed sites meeting particularly higher standards are further designated as National Historic Landmarks.
