Assa wollumbin, the Wollumbin pouched frog or Mount Wollumbin hip-pocket frog, is a species of small, terrestrial frog endemic to New South Wales, Australia. It is restricted to the slopes of Mount Warning (Wollumbin), where it inhabits rainforest habitat.
Previously considered a population of the pouched frog ("A. darlingtoni"), which was thought to be the only species in the genus, it was described as a new species in 2021 following a rangewide genetic analysis of "A. darlingtoni", which found the Wollumbin population to be sufficiently genetically distinct; it is also physically smaller than "A. darlingtoni". Despite its distinctiveness, it is separated from populations of "A. darlingtoni" by only ; in relation to the ancient Tweed Volcano, "A. darlingtoni" inhabits the former caldera wall while "A. wollumbin" inhabits the former volcanic plug that is now Mt. Wollumbin. As with "A. darlingtoni", it shares the unusual parental care where male individuals carry developing tadpoles in subcutaneous pouches on their hips. Due to its very small distribution, it has been recommended the species be classified as Critically Endangered.
