Al-Jarniyah Subdistrict (Arabic: ناحية الجرنية, romanized: nahiyah al-Jarniyah) is a subdistrict of Al-Thawrah District in Raqqa Governorate (Syria), approximately 75 kilometres (47 mi) west of Raqqa.

[1] Al-Jarniyah Subdistrict is bounded by Lake Assad to the West and South, Ayn al-Arab District of Aleppo Governorate to the North, and Raqqa District also of Raqqa Governorate to the East.

[5] During December 2016 the Syrian Democratic Forces drove ISIS out of most Al-Jarniyah Subdistrict.

With the help of US special forces, Bir Shallal and nearby villages in the north-east of the nahiyah were taken over in mid December,[6] soon followed by a corridor stretching to Wasta on Lake Assad which cut off the west of the nahiyah which was subsequently taken over.

[7] The largest town of the area, Mahmudli in the south west of the nahiyah, was taken over by the SDF at the start of 2017.
