Jules François Felix Fleury-Husson (17 September 1820, Laon, Aisne – 6 December 1889, Sèvres), who wrote under the name Champfleury, was a French art critic and novelist, a prominent supporter of the Realist movement in painting and fiction.

In 1843 Fleury-Husson moved to Paris. He met Charles Baudelaire and the next year started writing art criticism under the pen-name "Champfleury" for the journal L'Artiste. He was one of the first to promote the work of Gustave Courbet, in an article appearing in an issue of Le Pamphlet in 1848.
