The Sulaiman Mountains (Pashto: د سليمان غر; Balochi/Urdu/Persian: کوه سليمان Koh-e Sulaimān), or the Kesai Mountains (Pashto: د كسي غرونه), are a major geological feature of southeastern Afghanistan (Zabul, most of Loya Paktia and northeastern Kandahar province), South Waziristan, and most of northern Balochistan province of Pakistan. The Sulaiman Mountains form the eastern edge of the Iranian plateau where the Indus River separates it from the Indian Subcontinent. Bordering the Sulaiman Range to the north are the arid highlands of the Hindu Kush, where more than 50 percent of the lands lie above 2,000 meters.
In Balochistan, the most famous peaks of the Sulaiman Mountains are Takht-e-Sulaiman (3,487 meters), Taunsa Sharif, the Khilafat Hills (3,475 meters) in Ziarat, Kesai Ghar (3,444 meters) near Zhob and Zarghun Ghar (3,578 meters) near Quetta.
