Schmargendorf is a south-western locality (Ortsteil) of Berlin in the district (Bezirk) of Charlottenburg-Wilmersdorf. Until 2001 it was part of the former district of Wilmersdorf.

Berlin is both a city and one of Germany's federated states. Since the 2001 administrative reform, it has been made up of twelve districts, each with its own administrative body. However, unlike the municipalities and counties of other German states, the Berlin districts are not territorial corporations of public law with autonomous competencies and property, but simple administrative agencies of Berlin's state and city government, the City of Berlin forming a single municipality since the Greater Berlin Act of 1920. Thus they cannot be equated to US or UK boroughs in the traditional meaning of the term.
