Oder–Havel Canal, Navigation canal in Brandenburg, Germany

The Oder-Havel Canal runs 82.8 km from the Oder near Hohensaaten to the Havel south of Oranienburg, part of the 101.6 km Havel-Oder Waterway. It crosses Brandenburg on embankments, including the Ragöser Damm, where the water surface lies over 28 m above the valley below. Three locks and the Niederfinow boat lift handle a total height difference of about 45.7 m.

The canal was built in the early 1900s as the Hohenzollern Canal to replace an older route through the region. Work started in 1908 and finished in 1914, creating a modern link between river systems that had previously required longer detours.

The name changed with politics: opened in 1914 as the Hohenzollernkanal for Kaiser Wilhelm II, it was called Oder-Havel-Kanal in the GDR while West Berlin kept the old name, and the current name was settled after reunification. Towns on the route include Oranienburg, Eberswalde and Oderberg.

The canal runs 82.8 km from the Spandau lock in Berlin to the Hohensaaten locks on the Oder, with three locks and the Niederfinow boat lift covering a total level difference of 45.7 to 46.7 m. The lift replaced four 9 m lock steps built with the canal and kept ready until 1972; a larger lift, Niederfinow Nord, entered service in 2022.

The 1934 Niederfinow boat lift raises vessels 36 metres in a trough 85 metres long and 12 metres wide. It replaced four 9-metre locks built with the canal as a stopgap, kept ready until 1972 in case the lift failed. A larger lift beside it, decided in 1992, only entered service in 2022.
