Phascolonus is an extinct genus of giant wombat known from the Pliocene[1] and Pleistocene of Australia.

It is suggested to have had a preference for arid and semi-arid inland habitats, with a diet consisting of a high amount of low quality vegetation.

Though it likely had wide home-ranges, it probably did not stray far from fresh water sources.

[4] Abundant remains have been found in Pleistocene aged deposits from Lake Callabonna in South Australia.

[4][6] Phylogenetic analysis suggests that is closely related to the other giant wombat genera Ramsayia and Sedophascolomys.
