The Yellow-footed Rock-wallaby (Petrogale xanthopus) is a member of the macropod family (the marsupial family that includes the kangaroos, wallabies, tree-kangaroos, wallaroos, and others).

The Yellow-footed Rock-wallaby is grey-brown with a yellow striped tail, white underside, yellow forearms and yellow feet. A fully grown adult will stand 60 cm high and weighs 7-13 kg.

This rock-wallaby is found in western New South Wales, northwestern Victoria, the east of South Australia and even small bits of Queensland. It does not usually live in places near humans, for it prefers a rocky environment.

At least one subspecies of this nocturnal diprotodont (P. x. xanthopus) appears on the IUCN Red List of Threatened Species as Vulnerable. The subspecies has a population of only about 5,000-10,000 in Queensland, is present in small numbers in the Flinders Ranges of South Australia and known from only the Gap and Cotraundee Ranges in New South Wales.

The other subspecies (P. x. celeris) is listed at Near Threatened. This species prefers rock crevices and caves in isolated rock outcrops and ridges in semi-arid country. It is threatened by fox predation, competition with domestic and wild introduced species (particularly goats, rabbits, and sheep), and wildfires.
