Mongolian wild horse or Dzungarian horse is a rare and endangered horse native to the steppes of central Asia. At one time extinct in the wild, it has been reintroduced to its native habitat in Mongolia at the Khustain Nuruu National Park, Takhin Tal Nature Reserve, and Khomiin Tal.

Common names for this equine include takhi, Asian wild horse, and Mongolian wild horse. It is named after the Russian geographer and explorer Niko?aj Przewalski.

Most wild horses today, such as the American mustang or the Australian brumby, are actually feral horses descended from domesticated animals that escaped and adapted to life in the wild. Przewalski's horse has long been considered the only 'true' wild horse extant in the world, never having been domesticated.
