An Elbe tributary is any watercourse flowing into the Elbe River, Central Europe's second-longest German river (after the Rhine) at ~1,094 km (724 km in Germany). The Elbe rises in the Czech Krkonoše (Giant Mountains), flows through Bohemia, Saxony, Saxony-Anhalt, Brandenburg, Lower Saxony, Schleswig-Holstein, and empties into the North Sea at Cuxhaven.
