André Pieyre de Mandiargues (14 March 1909 – 13 December 1991) was a French writer born in Paris.

His novel La Marge (1967; Eng: The Margin) won the Prix Goncourt and was made into a film of the same name by Walerian Borowczyk in 1976.

Borowczyk also used Mandiargues' work for the first story included in his anthology film Immoral Tales.

His book Feu de braise (1959) was published in 1971 in an English translation by April FitzLyon called Blaze of Embers (Calder and Boyars, 1971).

Mandiargues was friends with motorcycle journalist Anke-Eve Goldmann, who was likely the inspiration for the main character 'Rebecca', as Goldmann was the first woman to ride a motorcycle with a one-piece leather racing suit, which she designed with German manufacturer Harro.
