The Ustyurt or Ust-Yurt (from Kazakh: Үстірт; Uzbek: Ustyurt; Turkmen: Üstyurt; Karakalpak: Ústirt — flat hill, plateau) is a transboundary clay desert shared by Turkmenistan, Uzbekistan and Kazakhstan.
It extends roughly 200,000 km2 (77,000 sq mi), with an average altitude of 150 m (490 ft). Its highest point rises to 370 m (1,200 ft) in the south-west. At its northeastern edge it drops steeply to the Aral Sea and the surrounding plain.
The Ustyurt Plateau is bounded by steep cliffs called chinks nearly from everywhere. In the east it is the former west shore of the Aral Sea, in the south its chink breaks to Kunya-Darya (Куня-Дарья) alluvial plain and the Uzboy valley, in the west to the Karynyaryk depression and to the North Caspian Sea Karakum sands, and in the north to the Caspian Depression.  Ustyurt chinks often have multicolored layers, with colors of pale pink, blue, clear white, etc., and can form fancy landscapes.
Kazakhstan created the Ustyurt Nature Reserve (223,300 hectares) in July, 1984 in the south of Mangystausky district in Eralievsky region. It preserves rare fauna and flora such as the Ustyurt Mountain sheep and the Saiga antelope. Among its features are Sherkala Mountain and the concretions found in the Torysh ('Valley of Balls') near the town of Shetpe.
