Dinavar (also spelled Dinawar and Daynavar; Persian: دینور) was a major town between the 7th and 10th centuries, located to the northeast of Kermanshah in western Iran.

Located in the centre of the ancient region of Media, Dinavar is first attested in history as a town founded by the Greek Seleucid Empire (312 BC–63 BC), but it may have been older.

[1] Under the Sasanian Empire (AD 224–651), Dinavar served as an important fortified place, and was reportedly attacked by the Khazars in the early 6th-century.

[2] During the reign of the Umayyad caliph Mu'awiya I (r. 661–680), the town was renamed Mah al-Kufa and made one of the two districts of Jibal (Media).

[1][2] Dinavar had some importance due to its geographical location, serving as the entrance to Jibal as well as a crossroad between the culture of Iran and that of the inhabitants on the other side of the Zagros Mountains.
