Édouard Georges Mac-Avoy (1905 – 1991) was a French artist and portraitist. Mac-Avoy studied in Switzerland where he received his baccalauréat. His artistic talent caused a brief hesitation between theatre and painting, but having chosen the latter, he entered the Académie Julian at the age of 18 and studied there with Paul Albert Laurens. In Paris, he frequented the house of Felix Vallotton and met Bonnard and Vuillard who showed an interest in his work.
Mac-Avoy made portraits of many writers, artists and politicians including André Gide, Pierre Larousse, Honegger, Mauriac, Picasso, de Gaulle, Béjart, and Johnny Hallyday. A friend of Henry de Montherlant, he illustrated several of that writer's luxury editions including La relève du Matin in 1952, La Ville dont le prince est un enfant in 1961 and Les Garçons in 1973.
