Paul Berthon (Paul Emile Berthon, 15 March 1872 in Villefranche-sur-Saône – 27 February 1934 in Paris) was a French artist who produced primarily posters and lithograph. Berthon's work is in the style of Art Nouveau, much like his contemporary Alphonse Mucha. His study of the decorative arts influenced his print making, influencing the strong lines and natural details that guided his art. The vast majority of Berthon's lithographed posters did not include advertisements and were meant to stand on their own.
