Interatheriidae is an extinct family of notoungulate mammals from South America. Interatheriids are known from the Late Paleocene or Eocene (Mustersan) to the Late Miocene (Huayquerian).^[1][2] These animals were principally small-sized, occupying a habitat like hares, marmots and vizcachas. The majority were very small, like rodents.

Interatheriidae is one of the mammal groups that best represent the fauna from the . Particularly Protypotherium with three species is characteristic of the formation: P.australe, P. praerutilum and P. attenuatum. Another well-known genus is Interatherium, particularly well represented by I. robustum.
