Sindh Sagar Doab (Panjabi; Punjabi: {{nq|سندھ ساگر دوآب, Sindh Sāgar Do'āb), sometimes shortened as Sagar Doab, is a tract of land in the Punjab region, lying between the Indus and Jhelum rivers, in present-day Pakistan. It, administratively, covers a huge portion of the western areas of the Punjab province and eastern Hazara Division.[1] It is one of the five major doabs of the Punjab and forms the north western portion of the region, covering the Hazara Hills, Galyat, Pothohar Plateau and Thal Desert.
It covers Attock District, Rawalpindi District, Jhelum District, Chakwal District, Mianwali District, Khushab District, Bhakkar District, Layyah District, Muzaffargarh District and Athara Hazari Tehsil and Ahmadpur Sial Tehsil of Jhang District..
Major areas in this doab include the Kala Chitta Range, Margalla and Murti Hills, Pothohar Plateau, Salt Range and Thal Desert.
Some major cities of this doab are Rawalpindi, Taxila, Attock, Chakwal, Jhelum, Pind Dadan Khan, Talagang, Mianwali, Bhakkar, Layyah, Muzaffargarh, Khushab and Quaidabad.
Of the Punjab doabs, the Sindh Sagar Doab is the largest in land area, but the poorest for agriculture, due to the presence of the Salt Range and Thal Desert.
The word doab is of Persian origin, signifying the region between two rivers.[2] According to Shaikh Abu'l-Fazl ibn Mubarak, the grand vizier of the Mughal emperor Akbar, and author of the Akbarnama, the names of the doabs were decided by Akbar.[3]
