Albert Guillaume (14 February 1873 – 10 August 1942) was a French painter and caricaturist.
Born in Paris, France, Albert Guillaume became a leading caricaturist during the Belle Époque. While remembered for his poster art, Guillaume also did oil paintings such as "Soirée parisienne," a portrait of Parisian dinner society. He created theater posters as well as advertising posters that were greatly influenced by the work of one of the preeminent poster painters, Jules Chéret.
