Gilles is a 1939 novel by the French writer Pierre Drieu La Rochelle.

After returning from the war, Gilles marries a Jewish woman for her wealth, becomes involved with the surrealist movement, develops his own fusion of Christianity and fascism, and joins the Nationalist faction to fight in the Spanish Civil War.

[3] The French critic Gaëtan Picon wrote: "Gilles is, without any doubt, one of the greatest novels of the century—and one of those books in which the disarming sincerity of a man rises to the grandeur usually reserved to literary transpositions.

"[3] The English journalist Will Self wrote that Gilles is "as good and unapologetic an account of what it was to be a fascist during this era as André Malaraux's Man's Fate is one of what it was to be a communist.

"[5] In 2024 the publishing house Tikhanov Library released the first of three volumes of an English translation of Gilles.
