Persian Iraq (; ), also spelled Persian Irak, is a historical term for the central-western region of Iran, including cities such as Isfahan, Ray, Qazvin, and Kashan. From the 11th to 19th centuries, the name Iraq referred to two neighbouring regions: Arabic Iraq (ʿIrāq-i ʿArab) and Persian Iraq (ʿIrāq-i ʿAjam). Arabic Iraq corresponded with ancient Babylonia (now central-southern Iraq), while Persian Iraq corresponded with ancient Media (now central-western Iran). The two regions were separated by the Zagros Mountains.
