Dorothy's surname is Gale--it's the same in the Wizard of Oz books. Gale. Interestingly enough, Dorothy's last name isn't given in the original novel of The Wonderful Wizard of Oz. Her last name is first mentioned in the 1902 stage version of the story Baum wrote a few years later: My name is Dorothy Gale. In the later Oz books, Baum kept the name but mercifully spared his readers the pun. The last name was also used in The Movie, Return to Oz, and other adaptations of the story.
