Robert Ardrey (born October 16, 1908, Chicago, Illinois—died January 14, 1980, South Africa) was an American playwright and screenwriter who returned to his academic training in anthropology and the behavioral sciences in the 1950s.
African Genesis (1961) and The Territorial Imperative, two of Robert Ardrey's most widely read works, as well as Desmond Morris' The Naked Ape (1967), were key elements in the public discourse of the 1960s that challenged earlier anthropological assumptions. Ardrey's ideas notably influenced Arthur C. Clarke and Stanley Kubrick in the development of 2001: A Space Odyssey, as well as Sam Peckinpah, to whom Strother Martin gave copies of two of Ardrey's books.
As a science writer for the informed non-specialist reader in paleoanthropology, which encompasses anthropology, ethology, paleontology and human evolution, Robert Ardrey was among the proponents of the hunting hypothesis and the killer ape theory.
Ardrey postulated that precursors of Australopithecus survived millions of years of drought in the Miocene and Pliocene epochs, as the savannah spread and the forests shrank, by adapting the hunting ways of carnivorous species. Changes in survival techniques and social organisation gradually differentiated pre-humans from other primates. Concomitant changes in diet potentiated unique developments in the human brain.
These themes have also been investigated in academia by, among others:
- Konrad Lorenz: On Aggression (1966)
- University of Chicago "Man the Hunter" symposium (1966): Richard B. Lee and Irven DeVore, eds., Man the Hunter: Symposium on Man the Hunter, University of Chicago. Chicago: Aldine Publishing.

- Erich Fromm: The Anatomy of Human Destructiveness (1973)

Robert Ardrey was the son of Robert Leslie Ardrey, an editor and publisher, and the former Marie Haswell. He graduated Phi Beta Kappa from the University of Chicago, where his mentor was Thornton Wilder. Ardrey was married to Helen Johnson, whom he met at the University, from 1938 until they divorced in 1960. They had two sons, Ross and Daniel. In 1960 Ardrey married the South African stage actress Berdine Grunewald, who later illustrated his books.

- Bruce Eder. "Robert Ardrey". Allmovie (The New York Times). "Equally comfortable dealing with literary editors such as Bennett Cerf or moguls like Darryl F. Zanuck, he also retained his credibility in the intellectual realm by authoring texts on anthropology, history, and sociology that remain widely respected decades after their publication. The widening dates between Ardrey's film projects came as a result of his increasing literary activity, as he began generating screenplays and novels on his own in the early 1950s and subsequently returned to his academic training in anthropology and the behavioral sciences. From the end of the 1950s, he kept his oar in both fields, film and academia, and occupied a virtually unique position in the Hollywood pecking order because of his dual career. In 1962, he took on the daunting task of turning the World War I-era novel The Four Horsemen of the Apocalypse into relevant entertainment for the early 1960s, authoring the screenplay for Vincente Minnelli's gargantuan 1962 all-star release."
