Emden was a light cruiser built by the Reichsmarine in the early 1920s. She was the only ship of her class and was the first large warship built in Germany after the end of World War I. She was built at the Reichsmarinewerft in Wilhelmshaven; her keel was laid in December 1921 and her completed hull was launched in January 1925. Emden was commissioned into the German fleet in October 1925.
