Sabkhat al-Jabbūl or Mamlahat al-Jabbūl or Lake Jabbūl (Arabic: سبخة الجبول‎‎) is a large, traditionally seasonal, saline lake and concurrent salt flats 30 km southeast of Aleppo, Syria, in the Bāb District of Aleppo Governorate. It is the largest natural lake in Syria and the second largest lake after the artificial Lake Assad. In 2009 the lake covered about 100 km2 (39 sq mi) and was relatively stable. The salt flats are extensive and can be seen from space. The area includes the Sabkhat al-Jabbul Nature Reserve, a protected waterfowl site.
