The Chatham raven was a large songbird native to the Chatham Islands (New Zealand). Another closely related raven occurred on the North Island and South Island of New Zealand, namely the New Zealand raven, C. antipodum. This was formerly included in C. moriorum, but is considered a distinct species today. A reconstruction of the species is in the Museum of New Zealand Te Papa Tongarewa, specimen MNZ S.036749.
