In Macbeth, what is the name of Macduff's wife?

In Macbeth, Macduff's wife is called Lady Macduff. Shakespeare never gives her a personal first name, so “Lady Macduff” is the canonical answer used in the play and in standard reference works. She appears briefly in Act 4, Scene 2, at Macduff's castle with their unnamed son.

Her scene follows Macduff's flight to England, where he hopes to help Malcolm challenge Macbeth. Lady Macduff sees his departure as abandonment and questions his loyalty, while her son responds with sharp intelligence and humor. Their domestic conversation briefly contrasts ordinary family life with the violence and suspicion consuming Scotland.

Macbeth sends murderers to Macduff's home because the witches have warned him to beware Macduff. The murderers kill Lady Macduff and her son, making their deaths one of the play's clearest examples of Macbeth's tyranny. Her name is often confused with Lady Macbeth's, but the two women occupy opposing moral positions: Lady Macbeth helps initiate Duncan's murder, while Lady Macduff and her child become innocent victims of Macbeth's rule. Later adaptations often expand Lady Macduff's small role and emphasize her as a foil to Lady Macbeth.
