Weißensee is a quarter in the borough of Pankow in Berlin, Germany, that takes its name from the small lake Weißer See within it. Before Berlin's 2001 administrative reform, Weißensee was a borough in its own right, consisting of the quarters of Weißensee, Heinersdorf, Blankenburg, Karow, and Stadtrandsiedlung Malchow. A fictional German-language TV series by the same name is set in the borough between 1980 and 1990 during the communist era.

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.
