Henri-Pierre Picou was a French painter. His oeuvre began with portraits and classical historical subject matter but he later moved on to allegorical and mythological themes.
He was an academic painter and one of the founders of the Neo-Grec school, along with his close friends Gustave Boulanger, Jean-Léon Gérôme, and Jean-Louis Hamon, also academic painters.
