Lady Macbeth is a leading character in William Shakespeare's tragedy Macbeth (c.1603–1607). As the wife of the play's tragic hero, Macbeth (a Scottish nobleman), Lady Macbeth goads her husband into committing regicide, after which she becomes queen of Scotland. After Macbeth becomes a murderous tyrant, she is driven to madness by guilt over their crimes, and commits suicide offstage.
