Amy Vanderbilt, American author (d. 1974)
Amy Osborne Vanderbilt (July 22, 1908 – December 27, 1974) was an American authority on etiquette. In 1952 she published the best-selling book Amy Vanderbilt's Complete Book of Etiquette. The book, later retitled Amy Vanderbilt's Etiquette, has been updated and is still in circulation. The most recent edition (ISBN 0-385-41342-4) was edited by Nancy Tuckerman and Nancy Dunnan. Its longtime popularity has led to its being considered a standard of etiquette writing.

She is also the author or collector of cooking materials, including the 1961 book Amy Vanderbilt's Complete Cook Book illustrated by Andy Warhol. This cookbook's illustrations are attributed to "Andrew Warhol", and predate Andy Warhol's first New York solo pop art exhibition. His illustrations are simple line drawings in pen and ink.
