Eutatus is an extinct genus of large armadillos of the family Dasypodidae. It was endemic to South America from the Early Miocene to Late Pleistocene, living from 17.5 Ma-11,000 years ago, with possible survival into the early Holocene (~ 7,500 BP) and existing for approximately . Based on carbon isotope ratios, it is thought to have been an herbivore that fed on grasses.
