Paul Berthon (Paul Berthon, 15 March 1872 in Villefranche-sur-Saône – 1909 in Paris) was a French artist who produced primarily posters and lithographs.^[1]

Berthon studied as a painter in Villefranche-sur-Saône before moving to Paris. He later enrolled at the Ecole Normale d'Enseignement de Dessin and received lessons in painting from Luc-Olivier Merson and lessons in decorative arts from Eugène Grasset. Grasset had a far greater influence on him, and he may be regarded as his pupil.

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.
