Linda Jo Goldway Keen (born 9 August 1940 in New York City, New York) is a mathematician and professor of mathematics and computer science at Lehman College since 1968. As a high school student she attended the Bronx High School of Science. She received her Bachelor of Science degree from the City College of New York, then studied at the Courant Institute of Mathematical Sciences, earning her Doctor of Philosophy in mathematics in 1964. She wrote her thesis on Riemann surfaces under the direction of Lipman Bers at NYU.

In addition to studying Riemann surfaces, Keen has worked in hyperbolic geometry, Kleinian groups and Fuchsian groups, complex analysis, and hyperbolic dynamics. In the field of hyperbolic geometry, she is known for the Collar lemma.

Keen has worked at the Institute for Advanced Study, Hunter College, University of California at Berkeley, Columbia University, Boston University, Princeton University, and the Massachusetts Institute of Technology, as well as at various mathematical institutes in Europe and South America. Since 1974 she has been a full professor at Lehman College and a member of the doctoral faculty at the CUNY Graduate Center.

Keen served as president of the Association for Women in Mathematics during 1985-1986 and as vice-president of the American Mathematical Society during 1992-1995. She served on the Board of Trustees of the American Mathematical Society from 1999-2009 and as Associate Treasurer from 2009-2011. In 1975, she presented an AMS invited address and in 1989 she presented an MAA joint invited address. In 1993 she was selected as a Noether Lecturer.

Keen worked with the mathematicians Paul Blanchard, Robert Devaney, Lisa Goldberg and Caroline Series among many others.

She has been honored with: AAUW Postdoctoral Fellowship Award, 1964-65 National Science Foundation Postdoctoral Fellow, 1964-65 Finish Mathematical Society Invited Foreign Speaker, JAN 1991 Lehman College Foundation Faculty Award, 1998 AWN Emmy Noether Lecturer, 1993 MAA Invited hour Address, Boulder CO, 1989 Merten Hasse Prize Committee 1990-92

She is married to Jonathan Brezin and resides in New York.
