The Werra, a river in central Germany, is the right-bank headwater of the Weser.
The Werra has its source near Eisfeld in southern Thuringia.
After 293 kilometres (182 mi) the Werra joins the river Fulda in the town of Hann. Münden, forming the Weser. If the Werra is included as part of the Weser, the Weser is the longest river entirely within German territory at 744 kilometres (462 mi).
