Zehlendorf is a locality within the borough of Steglitz-Zehlendorf in Berlin. Before Berlin's 2001 administrative reform Zehlendorf was a borough in its own right, consisting of the locality of Zehlendorf as well as Wannsee, Nikolassee and Dahlem. Zehlendorf contains some of the most remarked upon natural settings in Berlin, including parts of the Grunewald forest and the Schlachtensee, Krumme Lanke and Waldsee lakes. Additionally, it has large affluent residential neighborhoods, some with cobblestone streets and buildings that are over 100 years old.

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.
