Przewalski's horse (Equus ferus przewalskii), Mongolian: Takhi, is a rare and endangered subspecies of wild horse native to the steppes of central Asia, specifically Mongolia. At one time extinct in the wild (in Mongolia, the last wild Przewalski's horses had been seen in 1966), it has been reintroduced to its native habitat in Mongolia at the Khustain Nuruu National Park, Takhin Tal Nature Reserve, and Khomiin Tal.

Przewalski's horse is considered the only remaining truly wild "horse" in the world and may be the closest living wild relative of the domesticated horse.
