Löcknitz is a river in northern Germany (Mecklenburg-Vorpommern, Brandenburg and a few kilometres in Lower Saxony). The Löcknitz is a right tributary of the Elbe, its total length is 66 km. The Löcknitz originates south of Parchim, and flows through Karstädt, Lenzen, and Dömitz. The Löcknitz joins the Elbe in Wehningen (part of Amt Neuhaus), a few kilometres downstream from Dömitz. A different river Löcknitz arises in a protected valley in Eastern Brandenburg, contributing to Spree and then into Havel and Elbe as well.
