Leda Cosmides (born May 1957) is an American psychologist, who, together with anthropologist husband John Tooby, pioneered the field of evolutionary psychology.

Cosmides was born into a Greek family.^[1] Her parents, George Cosmides and Nasia Cosmides (née Murlas), founded the St George Greek Orthodox Church in Bethesda, Maryland.^[2]

Cosmides originally studied biology at Radcliffe College/Harvard University, receiving her BA in 1979. While an undergraduate, she was influenced by the renowned evolutionary biologist Robert L. Trivers, who was her advisor. In 1985, Cosmides received a PhD in cognitive psychology from Harvard. After completing postdoctoral work under Roger Shepard at Stanford University, she joined the faculty of the University of California, Santa Barbara in 1991, becoming a full professor in 2000.

In 1992, together with Tooby and Jerome Barkow, Cosmides edited The Adapted Mind: Evolutionary Psychology and the Generation of Culture. She and Tooby also co-founded and co-direct the Center for Evolutionary Psychology.

Cosmides was awarded the 1988 American Association for the Advancement of Science Prize for Behavioral Science Research,^[3] the 1993 American Psychological Association Distinguished Scientific Award for an Early Career Contribution to Psychology, a Guggenheim Fellowship, the 2005 National Institutes of Health Director's Pioneer Award, and the 2020 Jean Nicod Prize. In 2023 she was elected to the American Academy of Arts and Sciences.^[4]
