The Werra (German pronunciation: [ˈvɛʁa]), a river in central Germany, is the right-bank headwater of the Weser.

After 293 kilometres (182 mi) the Werra joins the river Fulda in the town of Hann.

Its valley, the Werratal, has many tributaries and is a relative lull between the Rhön Mountains and the Thuringian Forest.

Its attractions include Eiben Forest near Dermbach, an unusual sandstone cave at Walldorf, the deepest lake in Germany formed by subsidence (near Bernshausen), and Krayenburg, the ruins of a castle.

The towns and main settlements along the Werra are Hildburghausen, Meiningen, Bad Salzungen, Tiefenort, Merkers-Kieselbach, Vacha, Heringen, Philippsthal, Gerstungen, Wanfried, Eschwege, Bad Sooden-Allendorf, Witzenhausen and Hannoversch Münden.
