Mount Imeon is an ancient name for the Central Asian complex of mountain ranges comprising the present Hindu Kush, Pamir and Tian Shan, extending from the Zagros Mountains in the southwest to the Altay Mountains in the northeast, and linked to the Kunlun, Karakoram and Himalayas to the southeast. The term was used by Hellenistic-era scholars as "Imaus Mount", even though non-Greek in etymology, and predating Alexander the Great.
