Stanley Thomas Williams (25 October 1888 – 5 February 1956) was a scholar who helped to establish the study of American literature as an academic field during his teaching career at Yale University.
In 1935 he was awarded a Guggenheim Fellowship.
His most notable publication is a two-volume biography of Washington Irving but he is best remembered for changing the study of Herman Melville by strategically directing doctoral dissertations on his life and works.
