The Sulaiman Mountains or Kōh-e Sulaymān (; Balochi/Urdu/; Mountains of Solomon), are a north-south extension of the southern Hindu Kush mountain system, and rise to form the eastern edge of the Iranian Plateau, and the northeastern edge of the Balochistan Plateau. They are located in the Zabul, Kandahar and Loya Paktia regions of Afghanistan, and in Pakistan they extend over the northern part of Balochistan province, and some parts of southwestern Khyber Pakhtunkhwa and Punjab. Bordering the Sulaimans to the north are the arid highlands of Central Hindu Kush whose heights extend up to , and to the east are the Indus plains. Together with the Kirthar Mountains in southern Pakistan, they form what is known as the Sulaiman-Kirthar geologic province.
