Sabkhat al-Jabbūl or Mamlahat al-Jabbūl or Lake Jabbūl is a large, traditionally seasonal, saline lake and concurrent salt flats (sabkha) 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 Euphrates Lake. In 2009, the lake covered about 100 km2 (39 sq mi) and was relatively stable. The salt flats are extensive. The area includes the Sabkhat al-Jabbul Nature Reserve, a protected waterfowl site.
