Mansfield Park is the third published novel by Jane Austen, first published in 1814 by Thomas Egerton. A second edition was published in 1816 by John Murray, still within Austen's lifetime. The novel did not receive any public reviews until 1821.

The novel tells the story of Fanny Price, starting when her overburdened family sends her at age ten to live in the household of her wealthy aunt and uncle and following her development into early adulthood. From early on critical interpretation has been diverse, differing particularly over the character of the heroine, Austen's views about theatrical performance and the centrality or otherwise of ordination and religion, and on the question of slavery. Some of these problems have been highlighted in the several later adaptations of the story for stage and screen.
