The Elegance of the Hedgehog (French: L'Élégance du hérisson) is a novel by the Frenchnovelist and professor of philosophy Muriel Barbery. The book follows events in the life of a concierge, Renée Michel, whose deliberately concealed intelligence is uncovered by an unstable but intellectually precocious girl named Paloma Josse. Paloma is the daughter of an upper-class family living in the upscale Parisian apartment building where Renée works.

Featuring a number of erudite characters, The Elegance of the Hedgehog is full of allusions to literary works, music, films, and paintings. It incorporates themes relating to philosophy, class consciousness, and personal conflict. The events and ideas of the novel are presented through the thoughts and reactions, interleaved throughout the novel, of two narrators, Renée and Paloma. The changes of narrator are marked by switches of typeface. In the case of Paloma, the narration takes the form of her written journal entries and other philosophical reflections; Renée's story is also told in the first person but more novelistically and in the present tense.

First released in August 2006 by Gallimard, the novel became a publishing success in France the following year, selling over two million copies. It has been translated into more than forty languages, and published in numerous countries outside France, including the United Kingdom (Gallic Books, London) and the United States (Europa Editions, New York), and has attracted critical praise.
