The Wicked Witch of the West is a character in the classic children's novel The Wonderful Wizard of Oz (1900) by the American author L. Frank Baum, who is the evil ruler of the Winkie Country, the western region in the Land of Oz. She is inadvertently killed by the child Dorothy Gale with a bucket of water. In Baum's subsequent Oz novels, the Wicked Witch of the West is referred to occasionally.
Margaret Hamilton played the role of the witch in the classic 1939 film based on Baum's novel. Hamilton's characterization introduced green skin, a feature repeated in later literary and dramatic representations, including Gregory Maguire's 1995 revisionist novel Wicked (as well as the novel's 2003 stage musical adaptation and subsequent two-part film adaptation), the 2013 film Oz the Great and Powerful, and the television series Once Upon a Time.
