Dwight Davis), (30 December 1908 – 6 February 1965) was an American comparative anatomist and curator of zoology at the Chicago Natural History Museum.

He took a special interest in identifying the evolutionary relationships of the giant panda to  other mammals using anatomical studies. He took over 25 years on the study and published a comprehensive book on the topic just a couple of months before his death. He visited Borneo in 1950 on a collection expedition and visited Malaya in 1962 where he worked for 9 months at the University in Kuala Lumpur. Along with Rainer Zangerl, he was involved in translating Willi Hennig's influential work on phylogenetics into English which was published in 1966.
