The nail-tail wallabies (genus Onychogalea) are three species of macropod found in Australia. They are distinguished by a horny spur at the end of their tail. While the northern nail-tail wallaby is still common in the northern part of Australia, the crescent nail-tail is now extinct, and the bridled nail-tail is considered rare and endangered, with probably fewer than 1100 mature individuals in the wild. Nail-tail wallabies are smaller than many other wallabies.
