The SS Admiral Nakhimov (Russian: Адмирал Нахимов), launched in March 1925 and originally named SS Berlin III, was a passenger liner of the German Weimar Republic later converted to a hospital ship, then a Soviet passenger ship. On 31 August 1986, Admiral Nakhimov collided with the large bulk carrier Pyotr Vasev in the Tsemes Bay, near the port of Novorossiysk, Russian SFSR, and quickly sank.
