Equus lambei, commonly known as the Yukon horse or Yukon wild horse, is a species of the genus Equus. Equus lambei ranged across North America until approximately 10,000 years ago. Based on recent examinations of the mtDNA of Equus lambei remains, scientists have concluded that E. lambei was probably much like the extinct tarpan, also known as the Eurasian wild horse, and the living Przewalski's horse. A partial carcass of Equus lambei is on display at the Yukon Beringia Interpretive Centre in Whitehorse, Yukon.
In the Series 3 finale "Mammoth's Undertaking Journey II: The Eternal Frontier", a herd of a dozen Yukon Horses were brought to the park from Late Pleistocene North America 11,000 years ago. They reside in the Mammoth Tundra Enclosure with other ice age animals.
