The Unstrut is a river in Germany, tributary of the Saale. It originates in northern Thuringia near Dingelstädt (west of Kefferhausen in the Eichsfeld area). In its lower reaches, it flows for a short distance through Saxony-Anhalt and empties into the Saale near Naumburg. The total length of the Unstrut is 192 km. Towns along the Unstrut include Mühlhausen, Sömmerda, Bad Frankenhausen, Artern and Roßleben.

Together with the Saale, the Unstrut forms the winegrowing district of Saale-Unstrut. The well-known brand of sparkling wine, "Rotkäppchen" ("Little Red Riding Hood") is produced in the cellars of Freyburg. In 531, according to the Decem Libri of Gregory of Tours, the decisive battle between the Franconians and Thuringians took place along the Unstrut, which resulted in the destruction and annexation of the early medieval Thuringian kingdom by the Franconian empire.

The Gera is a tributary of the Unstrut.
