Grünauer BC 1917 is a German association football club from Grünau in the Treptow-Köpenick district of the city of Berlin.

The club was active under several different names in the separate East German football competition that emerged in the Soviet-occupied eastern half of the country after World War II.

Through its history in East German competition the club underwent several name changes, becoming TSG Grünau-Bohnsdorf in June 1949, and then Sportgemeinschaft Grünau in 1950.

The two clubs went their separate ways the next year with Grünau remaining largely out of sight in lower tier city competition until emerging in the II.

In December 1961, SG was again renamed, becoming BSG Deutsche Lufthansa Berlin, a Betriebssportgemeinschaft associated with the aviation industry in the city.
