Morris William Hirsch (born June 28, 1933) is an American mathematician, formerly at the University of California, Berkeley.

A native of Chicago, Illinois, Hirsch attained his doctorate from the University of Chicago in 1958, under supervision of Edwin Spanier and Stephen Smale.^[1] His thesis was entitled Immersions of Manifolds. In 2012, he became a fellow of the American Mathematical Society.^[2]

Hirsch had 23 doctoral students, including William Thurston, William Goldman, and Mary Lou Zeeman.
