Kaiserliche Werft Danzig was a German shipbuilding company founded in 1852 as Königliche Werft Danzig first, renamed to Kaiserliche Werft with the proclamation of the German Empire in 1871. Together with Kaiserliche Werft Kiel and Kaiserliche Werft Wilhelmshaven it was one of three shipyards which were responsible for maintenance, repair and construction of warships for the Imperial German Navy. With the end of World War I Kaiserliche Werft Danzig was closed in 1918, but soon opened again when Danziger Werft was founded on their site in 1919.
