Al Jawf (Arabic: الجوف Al-Jawf) is a governorate of Yemen. Its capital is Al Hazm.
As of April 2020, after the Houthi forces' 2020 offensive, nearly all the governorate is under Houthi control, except for Khabb wa ash Sha'af which is under the control of Al-Qaeda.
The Ramlat al-Sab'atayn (Arabic: رملة السبعتين, lit. 'Sand of the Two Sevens') is a desert region that corresponds with the northern deserts of modern Yemen (Al-Jawf, Marib, Shabwah governorates) and southwestern Saudi Arabia (Najran province).
It comprises mainly transverse and seif dunes and covers an area of about 100 by 240 kilometres (60 by 150 mi), roughly 26,000 square kilometres (10,000 sq mi).
