John McLean (1761 – October 16, 1823) was an American merchant most famous because of his will. The will was the subject of the Massachusetts Supreme Judicial Court case Harvard College v. Amory, which led to the Prudent man rule; left a bequest to Massachusetts General Hospital which led to McLean Hospital being named after him; and established the McLean Professor of Ancient and Modern History, a professorship at Harvard University.
