Cunampaia is a dubious genus of extinct mesoeucrocodylian. Fossils have been found from the Divisadero Largo Formation of Mendoza Province, Argentina, and date back to the Divisaderan regional South American Land Mammal Age of the lower Eocene epoch. Originally it was regarded as a gruiform bird, being only recently reassigned as a crocodylomorph. In 1968 it was placed in its own family, Cunampaiidae, which falls within the suborder Cariamae. Despite this classification, it has frequently been referred to as a phorusrhacid.
