SM U-112 was a Type U 93 submarine and one of the 329 submarines serving in the Imperial German Navy in World War I. U-112 was engaged in naval warfare and took part in the First Battle of the Atlantic. She was surrendered to the Allies at Harwich on 22 November 1918 and later transferred to Pembroke, earmarked for use in experiments. In the event, the boat was sold to M. Lynch and Son on 27 September 1920, and towed to Rochester, Kent, where the diesel engines were removed for use ashore. The hulk was re-sold to Upnor Shipbreaking on 25 October 1922 and broken up.
