Jack Maggs (1997) is a novel by Australia writer Peter Carey.

Set in 19th century London, Jack Maggs is a retelling of Great Expectations (1861) by Charles Dickens with Jack Maggs as a central character (instead of Abel Magwitch).

Jack Maggs was a foundling who was given in to foster care and trained to be a thief. After being betrayed, he is transported to the penal colony of New South Wales, where he does well and provides for his son in London, Henry Phipps (instead of Pip).

Jack Maggs has been adapted for the stage by South Australian born playwright Samuel Adamson and the play has been put on by the State Theatre Company of South Australia in Adelaide during November 2024.

Mark Saturno plays Jack Maggs and the story is told by another character who has a minor role in Great Expectations, Mercy Larkin (Ahunim Abebe), a housemaid.
