Kollikodontidae is an extinct family of early monotreme mammals known from the Cretaceous of Australia. Defining characteristics of kollikodontids include very specialized bunodont molars, which may indicate a diet of hard-shelled animals like mollusks in some species, and a somewhat narrow mandibular canal. The known genera have estimated body masses between 3.5–8 kilograms (7.7–17.6 lb).
