Nasir al-Din Artuq Arslan (ruled 1200–1239) was a ruler of the Artuqids of Mardin. The "Mardin branch" of the Artuqids ruled in Mardin and Mayyafariqin from 1101 to 1409, and were primarily descendants of Ilghazi and his brother Alp-Yaruq. His predecessor was his father Yuluq Arslan.
On the reverse of his coins dated AH 628 (1230 CE), Artuq Arslan inscribed the names of two overlords, the Abbasid Caliph al-Mustansir and the Ayyubid ruler al-Kamil. At that time, in 1229, the Ayyubids were allied with various Turkomans, including Artuq Aslan, in order to repel the offensive of the exiled Khwarazmian ruler Jalal al-Din from his base in Iranian Azerbaijan. They defeated Jalal al-Din and his Artuqid ally Rukhun al-Din Mawud (cousin of Artuq Aslan) in 1230.
