Przewalski's horse (pronounced or ; Khalkha , takhi; Ak Kaba Tuvan: [] dagy; Polish: ; Equus ferus przewalskii) or Dzungarian horse, is a rare and endangered subspecies of wild horse (Equus ferus) native to the steppes of central Asia. 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. The taxonomic position is still debated, and some taxonomists treat Przewalski's horse as a species, Equus przewalskii.
