Limnodynastidae, commonly known as the Australian ground frogs, is a family of frogs found in Australia, New Guinea, and the Aru Islands. They were formerly considered a subfamily of the Myobatrachidae, the other large radiation of terrestrial frogs in Australia, but are now considered a distinct family. Both Limnodynastidae and Myobatrachidae are thought to be the only members of the superfamily Myobatrachoidea.

The earliest fossils of this group are of Platypectrum casca from the Early Eocene.
