Löcknitz is a river in northern Germany (Mecklenburg-Vorpommern, Brandenburg and a few kilometres in Lower Saxony).
The Löcknitz originates south of Parchim, and flows through Karstädt, Lenzen, and Dömitz.
The Löcknitz joins the Elbe in Wehningen [de] (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.
