SS Atlantus is a concrete ship built by the Liberty Shipbuilding Company in Brunswick, Georgia, United States and outfitted by the American Shipbuilding Company. Although she was not finished in time for war service, as experimental EFC Design 1040, she was the first of twelve concrete ships for the World War I Emergency Fleet that finished construction, and the second concrete ship built in the United States (after the Faith). Her name was given by Edith Wilson.
