The Rothschild's rock-wallaby (Petrogale rothschildi), sometimes known as the Roebourne rock-wallaby, is a species of rock-wallaby found in Western Australia, in the Pilbara district and the Dampier Archipelago. It is not currently considered to be threatened, but is at risk from the red fox (Vulpes vulpes). Rothschild's rock-wallaby is one of the largest rock-wallabies, and also one of the most attractive. It is mostly a golden-brown colour with a greyish wash down its neck, which often has a purple appearance. It is a mostly nocturnal grass-eater found mostly around rocky ground.
