The Marinestation der Ostsee (Baltic Sea Naval Station) was a command of both the Imperial German Navy, and the Reichsmarine which served as a shore command for German naval units operating primarily in the Baltic Sea. The station was headquartered at Kiel and was a counterpart command to the Marinestation der Nordsee.
The original founding of the Baltic Sea Naval Station predates the existence of the modern German state. The station was first established 1854 in Danzig and was relocated to Kiel in March 1865. During these early years, the station was operated by the Prussian Navy.
The station was a major command during World War I and continued to exist, under the administration of the Weimar Republic, through the 1920s. After the Nazi Party took power in Germany, and established the Nazi state, the Reichsmarine continued to administer the Baltic station until the founding of the Kriegsmarine in 1935. At that time, the station command was renamed as the Kommandierender Admiral der Marinestation der Ostsee. This title remained until 1943 when the organizational name was changed to that of Marineoberkommando Ostsee.
