The Caspian tiger was a Panthera tigris tigris population native to eastern Turkey, northern Iran, Mesopotamia, the Caucasus around the Caspian Sea, Central Asia to northern Afghanistan and the Xinjiang region in western China. Until the Middle Ages, it was also present in southern Russia. It inhabited sparse forests and riverine corridors in this region until the 1970s. This population was regarded as a distinct subspecies and assessed as extinct in 2003.
