Jund Qinnasrin (Arabic: جند قنسرين, "military district of Qinnasrin") was one of five sub-provinces of Syria under the Umayyad and Abbasid Caliphate, organized soon after the Muslim conquest of Syria in the 7th century CE. Initially, its capital was Qinnasrin, but as the city declined in population and wealth, the capital was moved to Aleppo. By 985, the district's principal towns were Manbij, Iskandarun, Hamah, Shaizar, Ma'arrat al-Numan, Sumaisat, Jusiya, Wadi-Butnam, Rafaniyya, Lajjun, Mar'ash, Qinnasrin, al-Tinah, Balis, and Suwadiyyah.
