Angus John Bateman (1919–1996) was an English geneticist. He is most notable for his 1948 study{{Cite journal|last=Bateman|first=Angus J.|date=1948|title=Intra-Sexual Selection in Drosophila|journal=Journal of Heredity|volume=2|issue=Pt. 3|pages=349–68|doi=10.1038/hdy.1948.21|pmid=18103134|doi-access=free|bibcode=1948Hered...2..349B }} of evolutionary effects of sexual selection in fruit flies (Drosophila melanogaster) which established Bateman's principle, where in the evolutionary biology of most species, variability in reproductive success,, (or reproductive variance), is greater in males than in females.

Bateman was a member of the Communist Party of Great Britain during the Lysenko affair. He was an anti-Lysenkoist within the Party whilst writing in defense of Lysenko for non-Party audiences.{{Cite journal|last=Paul|first=Diane|date=1983|title=A War on Two Fronts: J. B. S.
