The Pilbara ningaui (Ningaui timealeyi), sometimes known as Ealey's ningaui, is a tiny species of marsupial carnivore found in Australia. It rarely exceeds 5.8 cm in body length, with a tail 6-7.6 cm long and a weight of 5-9.4g. This makes the Pilbara ningaui one of the smallest of all marsupials, surpassed only by the planigales.
