Schleuse Zerben, Navigation lock in Elbe-Parey, Germany.

Schleuse Zerben is a lock on the Elbe-Havel Canal between Zerben and Güsen in Saxony-Anhalt. It has two parallel chambers: a north chamber built from 1934 to 1938, 225 m long and 12 m wide, and a south chamber opened on 19 March 2018, 190 m long and 12.5 m wide. The north chamber has a maximum fall of 5.82 m.

Between 1926 and 1938 the Plauer Kanal and Ihlekanal were rebuilt as the Elbe-Havel-Kanal, and four older locks were merged into two: Zerben and Wusterwitz. Zerben's north chamber was built from December 1934 to the end of 1938 as a 225-metre tow-train lock. A second, southern chamber followed as part of Verkehrsprojekt Deutsche Einheit Nr. 17, ordered in March 2013 and opened to traffic on 19 March 2018.

The lock connects two major waterways and is used daily by cargo ships and pleasure boats. You can observe steady traffic here that shows how central this structure is to regional transport.

The lock is accessible to vessels during daytime hours, with larger ships needing to register in advance. Visitors can watch from the banks as boats pass through the chambers, especially when traffic is active.

The south chamber, released for traffic on 19 March 2018, was built 45 metres south of the north chamber and financed partly by the EU, which contributed 6.46 million euros of the 62 million euro expansion cost. It is 190 metres long and 12.50 metres wide, with a maximum fall of 5.50 metres.
