The Melikdom of Kashatagh (Armenian: Քաշաթաղի մելիքություն) was an Armenian melikdom (principality) which existed in the 15th–18th centuries. It was located along the Hakari River, on the southeastern section of the modern border of Armenia and Azerbaijan. The residences of the meliks were located in the villages of Kashataghk and Khnatsakh, in the west of the present Lachin District of Azerbaijan and the east of the present Syunik region of Armenia respectively.
