Steropodontidae is an extinct family of early monotreme mammals known from the Cretaceous of Australia.
== Taxonomy == Steropodon was initially placed in the crown group monotreme family Ornithorhynchidae but was subsequently made the type genus of Steropodontidae, its own monotypic family. The monotreme Teinolophos was suggested to also belong in this family, before also being placed in a distinct family. Parvopalus, known from the same locality as Steropodon, may be a steropodontid.
