The Crescent Nail-tailed Wallaby (Onychogalea lunata) was a wallaby that lived in the woodlands and scrubs of the west and centre of Australia. It had silky fur and, like other nail-tailed wallabies, had a horny spur at the tip of its tail. It was the size of a hare and was the smallest nail-tailed wallaby. When it was chased, it tended to seek refuge in a hollow tree. It entered at the bottom, clambered up and appeared at an opening high above.

The wallaby remained common, even in agricultural districts in the south-west of Western Australia, until about 1900. It had begun a steep decline by 1908, when the last wallaby was caught in the area. The last specimen of this wallaby to be collected alive was caught in a dingo trap on the Nullarbor Plain in 1927 or 1928. Mr W.A. Mills sent it to Taronga Zoo in Sydney and the animal ended up in the Australian Museum. The species survived in the more arid parts of its distribution until the 1950s and it is thought that it became extinct at about 1956, probably due to the spread of the fox.
