Stagodontidae is an extinct family of carnivorous metatherian mammals that inhabited North America during the late Cretaceous. Currently, the family includes two genera, Eodelphis and Didelphodon, which together include some five different species. Other extinct mammals, such as Pariadens, were once considered members of this family, but this is no longer the case. Stagodontids were some of the largest known Cretaceous mammals, ranging from 0.4 to 2.0 kilograms (0.88–4.41 lb) in mass.
