USS O-11 (SS-72) was an O-class submarine of the United States Navy. Her keel was laid down on 6 March 1916 by the Lake Torpedo Boat Company in Bridgeport, Connecticut. The later O-boats (O-11 through O-16) were designed by Lake Torpedo Boat to different specifications from the earlier ones designed by Electric Boat. They did not perform as well, and are sometimes considered a separate class. O-11 was launched on 29 October 1917 sponsored by Mrs. Bernard M. Baruch, and commissioned at New York City on 19 October 1918 with Lieutenant Commander F. W. Scanland in command.
