Samuel Ward McAllister (December 28, 1827 – January 31, 1895) was a popular arbiter of social taste in the Gilded Age of late 19th-century America. He was widely accepted as the authority as to which families could be classified as the cream of New York society (the Four Hundred). But his listings were also questioned by those excluded from them, and his own personal motives of self-aggrandisement were noted.
