The Akhal-Teke is a horse breed from Turkmenistan, where they are a national emblem. They have a reputation for speed and endurance, intelligence, and a distinctive metallic sheen. The shiny coat of palominos and buckskins 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 and Russia, although they are also found throughout Europe and North America. Akhal was the name of the line of oases along the north slope of the Kopet Dag mountains. It was inhabited by the Tekke tribe of Turkomans.

The Akhal-Teke typically stands between 14.2 and 16 hands (58 and 64 inches, 147 and 163 cm). These horses are well known for those individuals who have a golden buckskin or palomino color, a result of the cream gene, a dilution gene that also produces the perlino and cremello colors. A number of other colors are recognized, including bay, black, chestnut, and grey. Aficionados of the breed claim that the color pattern served as camouflage in the desert. Many Akhal-Tekes have a natural metallic sheen to their coat, particularly noticeable in those with cream gene colors.

The Akhal-Teke has a refined head with predominantly a straight or slightly convex profile, and long ears. It can also have almond-shaped or "hooded" eyes. The mane and tail are usually sparse. The long back is lightly muscled, and is coupled to a flat croup and long, upright neck. The Akhal-Teke possess sloping shoulders and thin skin. The breed is tough and resilient, having adapted to the harshness of Turkmenistan lands, where horses must live without much food or water. This has also made the horses good for sport. The breed is known for its endurance

The Akhal-Teke, due to its natural athleticism, can be a sport horse, good at dressage, show jumping, eventing, racing, and endurance riding.
