The Kulmerland was a supply ship of the Kriegsmarine that operated during the Second World War in the Indian Ocean and Pacific Ocean. It was named after the Kulmerland region of Prussia, with the city of Kulm, which in 1920 was made part of the Polish Corridor. She supplied German auxiliary ships (surface raiders) such as the Kormoran, Orion and Komet, for a time disguised as a Japanese merchant ship Tokyo Maru. Kulmerland was built in 1928 at Deutsche Werft, Hamburg, for the Hamburg America Line, operating on the North Atlantic route.
