Ferry transport forms part of the transport network of Berlin due to the city's extensive network of rivers, lakes, and canals. 6 routes operate within the city boundaries and one serves the city of Potsdam, which are part of the common public transport tariff run by the Verkehrsverbund Berlin-Brandenburg (VBB).

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.
