The central rock rat (Zyzomys pedunculatus), also known as the central thick-tailed rock-rat, Macdonnell Range rock-rat, Australian native mouse, rat à grosse queue (French), or rata coligorda (Spanish), is a species of rodent in the family Muridae that is found only in Australia. The rats have been found in rocky outcrops and on mountainsides with loose stones, as well as hilly grasslands and low open shrubland or woodland. Historically, Z. pedunculatus is only known to be found in a 77 km length of the West MacDonnell Ranges, Northern Territory. The species has previously been recorded from living animals or cave deposits in Northern Territory at Uluru-Kata Tjuta National Park, Illamurta (James Range), Haast's Bluff (West MacDonnell Ranges), Mount Liebig, Napperby Station, Devils Marbles, The Granites (Tanami Desert), and the Davenport Range. It is known from cave deposits in the Cape Range, Western Australia.
