The Akhal-Teke (/ˌækəlˈtɛk/ or /ˌækəlˈtɛki/; from Turkmen Ahalteke, [axalˈteke]) is a Turkmen horse breed. They have a reputation for speed and endurance, intelligence, and a distinctive metallic sheen. The shiny coat of the breed led to their nickname, "Golden Horses". These horses are adapted to severe climatic conditions and are thought to be one of the oldest existing horse breeds. There are currently about 6,600 Akhal-Tekes in the world, mostly in Turkmenistan, although they are also found throughout Europe and North America. Akhal is the name of the line of oases along the north slope of the Kopet Dag mountains in Turkmenistan. It has been inhabited by the Tekke tribe of Turkmens.
