John Clark Murray was a Scottish philosopher and professor. He held the Chair of Mental and Moral Philosophy at Queen's University from 1862 to 1872, and at McGill University from 1872 until 1903. During his academic career, Murray became the first professor at Queen's to offer courses to women; however, his equality advocacy caused unrest among the male professors. He was married to Margaret Polson Murray who founded the Imperial Order Daughters of the Empire.
