Irving Marmer Copi (born Copilovich, July 28, 1917, Duluth, Minnesota–August 19, 2002, Honolulu, Hawaii) was an American philosopher, logician, and university textbook author.
Copi taught at the University of Illinois, the United States Air Force Academy, Princeton University, and the Georgetown University Logic Institute, before teaching logic at the University of Michigan, 1958–69, and at the University of Hawaii at Manoa, 1969-90.
Copi is probably best known as the author of Introduction to Logic and Informal Logic, both widely used, with the former currently in its 14th edition.
