Muş Province (Turkish: Muş ili; Armenian: Մուշի մարզ, romanized: Mushi marz; Kurdish: Parêzgeha Mûşê is a province in the east Anatolia region of Turkey. Its area is 8,718 km2, and its population is 399,202, down from 453,654 in 2000. The provincial capital is the city of Muş. Another town in Muş province, Malazgirt, is famous for the Battle of Manzikert of 1071.

The Battle of Manzikert or Malazgirt was fought between the Byzantine Empire and the Seljuk Empire on 26 August 1071 near Manzikert, theme of Iberia. The decisive defeat of the Byzantine army and the capture of the Emperor Romanos IV Diogenes played an important role in undermining Byzantine authority in Anatolia and Armenia, and allowed for the gradual Turkification of Anatolia. Many Turks, travelling westward during the 11th century, saw the victory at Manzikert as an entrance to Asia Minor.
