Abū Muḥammad al-Ḥasan ibn Yūsuf al-Makzūn al-Sinjārī, better known simply as al-Makzun al-Sinjari () (b. 1188 or 1193 — d. 1240), was a paramount military, religious and literary figure in Alawite history and tradition. Al-Makzun was well-educated in Arabic poetry and Shia Islam. Descended from a line of emirs of Sinjar, he succeeded his father as emir of the town in 1205. Many Alawites from Sinjar migrated to the mountains around Latakia during the time of his father. The Alawites of these mountains later appealed for al-Makzun's intervention amid their struggles with the Kurds and Nizari Ismailis. Al-Makzun led an expedition to relieve the Alawites after many were massacred in the Sahyun fortress. Between 1218 and 1222, he and his sons captured the forts of Abu Qubays, which became al-Makzun's seat of power, al-Marqab, al-Ulayqa and Baarin. He ultimately drove out most of the Kurds and Ismailis from the mountains, consolidating the Alawite presence. In the following years, he penned a number of Alawite religious books.
