Zehdenick is a town in the Oberhavel district, in Brandenburg, Germany. It is situated on the river Havel, 26 kilometres southeast of Fürstenberg/Havel, and 51 kilometres north of Berlin (centre). Since 31 July 2013, the city has the additional appellation "Havelstadt".

The Havel is a river in northeastern Germany, flowing through the states of Mecklenburg-Vorpommern, Brandenburg, Berlin and Saxony-Anhalt. The 325 kilometres (202 mi) long Havel is a right tributary of the Elbe. However, the direct distance from its source to its mouth is only 94 kilometres (58 mi). For much of its length, the Havel is navigable; it provides an important link in the waterway connections between the east and west of Germany, as well as beyond.
