Pierre-Jean-Baptiste Chaussard (29 January 1766, Paris β 30 September 1823), known as Publicola Chaussard, was a French writer, art critic, poet, revolutionary, politician and follower of Theophilanthropy.
According to Michaud in his Biographie universelle, Chaussard was "a writer who would perhaps have failed to make a lasting reputation if he had lived under other circumstances".In 1809 he was elected a correspondent, living abroad, of the Royal Institute of the Netherlands.
