Hennigsdorf is a town in the district of Oberhavel, in Brandenburg, in eastern Germany. It is situated north-west of Berlin, just across the city border, which is formed mainly by the Havel river.

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.
