Ali ibn al-Husayn ibn Ali ibn Hanzala (Arabic: علي بن الحسين بن علي بن حنظلة, romanized: ʿAlī ibn al-Ḥusayn ibn ʿAlī ibn Ḥanẓala) was the tenth Tayyibi Isma'ili Da'i al-Mutlaq in Yemen, from 1284 to his death in 1287.[1]
He was the son of al-Husayn, the ma'dhun (senior deputy) to his predecessor, the ninth Da'i, also named Ali ibn al-Husayn, and grandson of the sixth Da'i, Ali ibn Hanzala.[1] Ali and his grandfather belonged to the Banu Hamdan and were the only ones to break the monopoly of the Qurayshi Ibn al-Walid family on the office of Da'i al-Mutlaq during the 13th century.[2] He was succeeded by another Ibn al-Walid, Ibrahim ibn al-Husayn.[1]
