Tapirus polkensis, the pygmy tapir, is a small prehistoric tapir that lived in North America during the late Miocene and early Pliocene. T. polkensis may have lived in swamps, where it would have been preyed on by ancestors of modern American crocodiles. T. polkensis had an estimated mass of around 125 kg (276 lb), making it smaller than any extant tapir.
The Gray Fossil Site in northeast Tennessee is home to the world's largest known fossil assemblage of T. polkensis.
