Darwin College is a constituent college of the University of Cambridge. Founded on 28 July 1964, Darwin was Cambridge University's first graduate-only college, and also the first to admit both men and women. The college is named after the family of Charles Darwin who previously owned some of the land, Newnham Grange, on which the college now stands.

The college has between 650 and 800 students, mostly studying for PhD or MPhil degrees with strengths in the sciences, humanities, and law. Darwin is the largest graduate college in Cambridge. Darwin's sister college at Oxford University is Wolfson College.

Members of Darwin College are termed Darwinians and alumni include British primatologist and anthropologist Jane Goodall, American conservationist Dian Fossey, Barbadian Governor-General Elliott Belgrave, Nobel Prize winners Elizabeth Blackburn, Eric Maskin and John Clarke, Solicitor-General of the United States Paul Clement, Global Energy Prize winning scientist Thorsteinn I. Sigfusson, and Pulitzer Prize nominated neurosurgeon Paul Kalanithi.
