SMS M85 was a M1916 type minesweeper built for the Imperial German Navy during the First World War by the Emden shipyard Nordseewerke, being launched on 10 April 1918 and entering service on 2 October that year. M85 survived the remainder of the war, and was passed on to the Reichsmarine, the navy of the Weimar Republic and then to the Nazi German Kriegsmarine. The outbreak of the Second World War saw M85 supporting the German invasion of Poland in September 1939, and she was sunk by a Polish mine on 1 October 1939 in one of the last acts of the Polish campaign.
