Fanny Young Cory (1877–1972) was an American book illustrator and graphic artist of the late nineteenth and early twentieth centuries. She supplied illustrations for the first editions of two of L. Frank Baum's books, The Master Key (1901) and The Enchanted Island of Yew (1903), as well as his short story "The Bad Man." Beyond the bounds of Baum's canon, she illustrated a wide range of the popular literature of the day, on humorous as well as serious subjects, including work for the prominent children's periodical St. Nicholas Magazine.
