Peligrotherium is an extinct meridiolestidan mammal from the Paleocene of Patagonia, originally interpreted as a stem-ungulate (though it did co-exist with early meridiungulates).

Its remains have been found in the Salamanca Formation.

It is a member of Mesungulatoidea, a clade of herbivorous meridiolestidans with molars that had rounded (bunodont) cusps.

[3][4] A biomechanical study finds Peligrotherium to be a herbivore functionally similar to the black rhino.
