Lady Macbeth is a leading character in William Shakespeare's tragedy Macbeth (c.1603–1607). 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. Later, however, she suffers pangs of guilt for her part in the crime, which drives her to sleepwalk. She dies off-stage in the last act, an apparent suicide.
