Pierre-François "David" Beauchard (born 9 February 1959), who uses the pen name David B., is a French comic book artist and writer, and one of the founders of L'Association.
After studying advertising at the Duperré School of Applied Arts in Paris, Beauchard began working in comics in 1985 (Pas de samba pour capitaine Tonnerre), and wrote and illustrated stories in numerous magazines, including Okapi, À suivre, Tintin Reporter, and Chic. His distinctive black-and-white style was influenced by Georges Pichard and Jacques Tardi, among others.
In 1990, he co-founded the independent publisher L'Association, which became a major force in French small-press comics. His comics appeared in the L'Association anthology magazine Lapin and in numerous small-format books. Much of his work in the 1990s was dream art, collected in le Cheval blême and les Incidents de la nuit.
