USCGC Eagle (WIX-327), formerly the Horst Wessel and also known as the Barque Eagle, is a 295-foot (90 m) barque used as a training cutter for future officers of the United States Coast Guard. She is one of only two active commissioned sailing vessels in the United States military today, along with USS Constitution which is ported in Boston Harbor. She is the seventh Coast Guard cutter to bear the name in a line dating back to 1792, including the Revenue Cutter Eagle.

A barque, barc, or bark is a type of sailing vessel with three or more masts and fore mast, mainmast and additional masts rigged square and only the aftmost mast rigged fore and aft. Sometimes, the mizzen is only partly fore-and-aft rigged, bearing a square-rigged sail above.
