The Unstrut is a river in eastern Germany and a left tributary of the Saale. It originates in northern Thuringia near Dingelstädt (west of Kefferhausen in the Eichsfeld area) and its catchment area is the whole of the Thuringian Basin. It breaks out of the basin through the Thuringian Gate west of Heldrungen and, in its lower reaches, flows through Saxony-Anhalt before emptying into the Saale near Naumburg. The total length of the Unstrut is 192 kilometres (119 mi).
