The Lauter (in its upper course also: Wieslauter) is a river in Germany and France.
The Lauter is a left tributary of the Rhine. Its length is 55km (34miles), of which 39 km is in France and on the France–Germany border. It is formed by the confluence of two headstreams (Scheidbach and Wartenbach) north of Hinterweidenthal in the Palatine Forest in the German state of Rhineland-Palatinate. It flows through Dahn, crosses the border with France, flows through Wissembourg, and then forms the French-German international boundary until its confluence with the Rhine near Lauterbourg and Neuburg am Rhein.
