The History of Tom Jones, a Foundling, often known simply as Tom Jones, is a comic novel by English playwright and novelist Henry Fielding. It is a Bildungsroman and a picaresque novel. It was first published on 28 February 1749 in London and is among the earliest English works to be classified as a novel. It is the earliest novel mentioned by W. Somerset Maugham in his 1948 book Great Novelists and Their Novels among the ten best novels of the world.

The novel is highly organised despite its length. Samuel Taylor Coleridge argued that it has one of the "three most perfect plots ever planned", alongside Oedipus Tyrannus and The Alchemist. It became a best seller with four editions published in its first year alone. It is generally regarded as Fielding's greatest book and as an influential English novel.
