Jacques Fontanille (born 1948) is a French semiotician who is one of the main exponents of the Paris School of Semiotics. He has authored or co-authored ten books and a number of articles or book chapters whose topics span theoretical semiotics, literary semiotics, and semiotics of the visual. A former student and collaborator of the founder of the Paris School of Semiotics, Algirdas Julien Greimas, Fontanille is one of the main continuators of Greimas' research program as he collaborated with him in his last published works, and assisted him in the administering and organizing of the Inter-Semiotic seminar at the École des Hautes Etudes en Sciences Sociales (EHESS) in Paris. After Greimas' death, the course continued under Fontanille's mantle until it became his own seminar at the Institut Universitaire de France.
