Graciela Chichilnisky (born 1944) is an Argentine American mathematical economist and an authority on climate change. She is a professor of economics at Columbia University.

Chichilnisky was born in Buenos Aires, Argentina, the daughter of Russian Jewish immigrants. She had a child during high school. In July 1966 a military coup occurred; the Argentine military violently closed scientific faculties at the University of Buenos Aires on July 29 during La Noche de los Bastones Largos (The Night of the Long Batons). Without having any undergraduate degree, Chichilnisky matriculated in the doctoral program in mathematics at the Massachusetts Institute of Technology, where she was supported by a fellowship from the Ford Foundation. She then moved to the University of California, Berkeley in 1968, where she completed her Ph.D. in mathematics in 1971, writing her thesis under the supervision of Jerrold E. Marsden. She then earned a second Ph.D. in economics in 1976 under the supervision of Gérard Debreu, a mathematical economist and Nobel laureate.

After postdoctoral studies at Harvard University, she accepted a position as an associate professor at Columbia in 1977, and received tenure there in 1979. While based at Columbia University, she was UNESCO Professor of Mathematics and Economics from 1995 to 2008. She held a chair in economics at the University of Essex from 1980 to 1981. She has also been a visiting professor at many other universities.
