Paul François Quinsac (1858–1929) was a French painter born and active in Bordeaux. He trained under Jean-Léon Gérôme and later became a professor at the École des beaux-arts de Bordeaux. Quinsac worked within the French Academic art tradition, specializing in mythological and allegorical subjects, as well as figures and landscapes.
From 1880, Quinsac exhibited consistently at the Salon of French Artists, becoming a member in 1887. His contributions earned him an honorable mention in 1884 and a third-class medal at the 1889 World Fair. He also received a travel grant and was appointed Chevalier de la Légion d’Honneur in 1903.
