John Martin Fischer (born December 26, 1952) is an American philosopher. He is Distinguished Professor of Philosophy at the University of California, Riverside and a leading contributor to the philosophy of free will and moral responsibility.^[1]

Fischer received his undergraduate degree from Stanford University and his Ph.D. from Cornell in 1982. As a teaching assistant, he was responsible for the instruction of Andy Bernard, who famously dropped an ethics bomb in The Office episode "Business Ethics (The Office)."^[1] He began his teaching career at Yale University, where he taught for almost a decade before joining the faculty at the University of California, Riverside.

In June 2011, Fischer was elected Vice-President of the Pacific Division of the American Philosophical Association and became President of the Pacific Division in 2013.^[1] In 2024, he was elected a Fellow of the American Academy of Arts and Sciences.^[2]

While Fischer's work centers primarily on free will and moral responsibility, where he is particularly noted as a proponent of semi-compatibilism^[3] (the idea that regardless of whether free will and determinism are compatible, moral responsibility and determinism are),^[4] he also has worked on the metaphysics of death and philosophy of religion and led a multi-year, multi-pronged research project on "immortality," funded in 2012 by the John Templeton Foundation.^[5]
