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.
