Mount Ḥaṣṣ or Mount Aḥaṣṣ (; northern Syrian vernacular: çabal ÃÂl-ḤÃÂṣṣ) is a 500-metre-high plateau (maximum height 638 m) on the northern fringe of the Syrian Desert. It is located in the Safërah District of Aleppo Governorate in Syria.
The plateau extends for with a width of about on the western side of Lake Jabboul from Safërah in the north to Sabkhat KharÃÂyij () and Sabkhat ḤammÃÂm () in the south. To the east lie the Qinnasrën plain (southern Aleppo plain) and the Maá¹Âkh lowland. A lesser elevation called Mount Shabëth () (highest point 360 m) is found in the southeast, beyond which lie Sabkhat Shabëth (). The plain of KhunÃÂá¹£ir separates between Mount Ḥaṣṣ and Mount Shabëth.
The area has more than 150 villages inhabited by Bedouins or people of Bedouinic ancestry. It is one of the poorest regions in Syria. A development project aims to improve living standards.
An ancient fortress dating to classical antiquity has been recently uncovered on Mount Ḥaṣṣ.
