Nur ad-Din Muhammad (r. 1175–1185 CE) was a member of the Artuqid dynasty, and the son of Fahkr al-Din Qara Arslan (Kara Arslan).
Nur ad-Din Muhammad was the Artuqid ruler of the Diyar Bakr, the northernmost region of Mesopotamia. In 1179 he received Saladin's protection against the Sultanate of Rum, with whom he had been feuding. In 1183 Saladin granted him the recently conquered Amida in return for his assistance against Mosul.
