Ivan Clarence Carnaby (24 July 1908 – 1974) was an Australian farmer, naturalist and ornithologist.
He was born in Subiaco, Western Australia.
He also made several botanical collecting journeys with Henry Steedman.
Carnaby first suggested the existence of more than one kind of white-tailed black-cockatoo in the 1930s, something later confirmed by research.
