SM UB-112 was a German Type UB III submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. She was commissioned into the German Imperial Navy on 16 April 1918 as SM UB-112.[Note 1]

UB-112 was surrendered to the Allies at Harwich on 24 November 1918 in accordance with the requirements of the Armistice with Germany; she was used for explosives trials off Falmouth on 20 November and 1 December 1920, after which the boat was dumped on Castle Beach. The wreck was sold for scrap to R. Roskelly & Rodgers on 19 April 1921 for £125, but remains survive in situ.[4]
