Jules François Felix Fleury-Husson (17 September 1821, in Laon, Aisne – 6 December 1889, in Sèvres), who wrote under the name Champfleury (French pronunciation: [ʃɑ̃fløʁi]), was a French art critic and novelist, a prominent supporter of the Realist movement in painting and fiction.

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.

He wrote about the Le Nain brothers[1] and Maurice Quentin de La Tour.

In 1869 his book Les Chats, a series of essays about cats including portrayals of cats by prominent artists of the time, was published by Librairie de la Société Botanique de France, edited by J. Rothschild.
