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. The Pilbara ningaui is found mostly in the Pilbara region of Western Australia. It is partly arboreal, and differs from other ningauis in its smaller size and rufous-tinted face.
