Elphaba Thropp (/ˈɛlfəbə ˈθrɒp/) is the protagonist in the 1995 novel Wicked: The Life and Times of the Wicked Witch of the West by Gregory Maguire, in its musical theatre adaptation Wicked, and in the musical's two-part film adaptation. The character is identified with the Wicked Witch of the West from L. Frank Baum's 1900 novel The Wonderful Wizard of Oz. In the Baum novel, the Witch is unnamed and little is explained about her life; Wicked creates a backstory for her and explores the world of The Wizard of Oz from her perspective. Elphaba is modeled after Margaret Hamilton's portrayal in the 1939 film The Wizard of Oz: green-skinned, clad entirely in black and wearing a tall peaked hat. Maguire formulated the name "Elphaba" from the pronunciation of Baum's initials—"L.F.B."
