Mount Ḥaṣṣ or Mount Aḥaṣṣ (Arabic: جبل الحص or جبل الأحص; northern Syrian vernacular: ǧabal əl-Ḥəṣṣ) is a 500-metre-high plateau (maximum height 638 m) on the northern fringe of the Syrian Desert.

The plateau extends for 60 km (37 mi) with a width of about 30 km (19 mi) on the western side of Lake Jabboul from Safīrah in the north to Sabkhat Kharāyij (Arabic: سبخة الخرايج) and Sabkhat Ḥammām (Arabic: سبخة همام) in the south.

A lesser elevation called Mount Shabīth (Arabic: جبل شبيث) (highest point 360 m) is found in the southeast, beyond which lie Sabkhat Shabīth (Arabic: سبخة شبيث).

A development project aims to improve living standards.
