George Bennett FRCS FLS FZS[1] (31 January 1804 – 29 September 1893) was an English-born Australian physician and naturalist, winner of the Clarke Medal in 1890.

In 1832 his friend Richard Owen was engaged in examining the structure and relations of the mammary glands of the Ornithorhyncus, and Bennett became so interested that on leaving England shortly afterwards for Australia he determined while in that country to find a solution of the question.

He kept up a correspondence with his early friend Sir Richard Owen, to whom he had sent the first specimens of the chambered nautilus to arrive in England, and with Darwin and other scientists of the time.

[3] In addition to the nautilus, Bennett brought a Sumatran gibbon specimen to England as well as a young Erromangan girl named Elau, who was the first native of the New Hebrides to visit Europe.

The variety of his interests may be suggested by the fact that he published in 1871 papers on "A Trip to Queensland in Search of Fossils" and on "The Introduction, Cultivation and Economic Uses of the Orange and Others of the Citron Tribe".

The Royal Society of New South Wales awarded Bennett the Clarke memorial medal in 1890 for his valuable contributions to the natural history of Australia.
