UB-145 was a German Type UB III submarine or U-boat built for the German Imperial Navy (German: Kaiserliche Marine) during World War I. Incomplete at the end of the war, she was surrendered to the Allies at Harwich on 27 March 1919, and then taken to Chatham Dockyard as a potential subject for experimental work, but was never so-employed. She was sold to M. Lynch & Sons on 22 July 1920 for £2,000, and towed to Rochester, Kent. After being stripped of any reusable material, the hulk was dumped in shallow water in the Medway estuary, along with those of UB-144 and UB-150. The remains of all three - partly broken up in-situ during 1939–45, with one significantly better preserved than the other two - remain visible, but it is unclear which wreck is which.
