Mina Spiegel Rees (2 August 1902, Cleveland, Ohio – 25 October 1997, New York City) was an American mathematician. She was the first female President of the American Association for the Advancement of Science (1971) and head of the mathematics department of the Office of Naval Research of the United States.
She was valedictorian at Hunter College High School in New York City. She graduated Summa cum Laude with a math major at Hunter College in 1923. She received a masters in mathematics from Columbia University in 1925. At that time she was told unofficially that "the Columbia mathematics department was not really interested in having women candidates for Ph.D's". She started teaching at Hunter College then took a sabbatical to study for the doctorate at the University of Chicago in 1929. She earned her doctorate in 1931 with a thesis on "Division algebras associated with an equation whose group has four generators," published in the American Journal of Mathematics, Vol 54 (Jan. 1932), 51-65. Her advisor was Leonard Dickson.

Award for Distinguished Service to Mathematics in 1962 from the Mathematical Association of America. This award was made "for outstanding service to mathematics, other than mathematical research" and for "contributions [that] influence significantly the field of mathematics or mathematical education on a national scale."
In 1983 Rees was awarded the Public Welfare Medal from the National Academy of Sciences "for her contributions to the scientific enterprise, especially in mathematics, astronomy, and computer sciences, from wartime, through the transition from war to peace, and continuing today."
Kings Medal for Service in the Cause of Freedom (Britain) and the President's Certificate of Merit (USA) for her important contributions during World War II.
