The Hawaiian crow or ā (Corvus hawaiiensis) is a species of bird in the crow family, Corvidae, that is currently extinct in the wild. It is about the size of the carrion crow at 48–50 centimetres (19–20 in) in length,<ref name=":0" /> but with more rounded wings and a much thicker bill. It has soft, brownish-black plumage and long, bristly throat feathers; the feet, legs and bill are black. Today, the Hawaiian crow is considered the most endangered of the Corvidae family.<ref name=":2">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> They are recorded to have lived up to 18 years in the wild, and 25 years in captivity.

The species is known for strong flying ability and resourcefulness, and the reasons for its extirpation are not fully understood. It is thought that introduced diseases, such as Toxoplasma gondii, avian malaria (Plasmodium relictum), and fowlpox, were probably a significant factor in the species' decline.<ref name="FactSheet">{{#invoke:citation/CS1|citation |CitationClass=report }}, 16 MB file.
