Isma'il ibn Salih ibn Ali al-Hashimi

Ismāʿīl ibn Ṣāliḥ ibn ʿAlī al-Hāshimī (إسماعيل بن صالح بن علي الهاشمي) was an eighth century Abbasid governor of Egypt and Aleppo.

A member of the Abbasid family, he was a son of Salih ibn Ali and a first cousin of the first two Abbasid caliphs al-Saffah ((r. 750 – 754)) and al-Mansur ((r. 754 – 775)). During the reign of Harun al-Rashid ((r. 786 – 809)) he was appointed as governor of Egypt in 797. After an administration lasting slightly less than a year, he was dismissed from that province and instead posted to Aleppo and Qinnasrin, which he proceeded to hold for an unspecified length of time.
