Joseph ben Samuel Bonfils (fl. middle of the 11th c.) was a French rabbi, Talmudist, Bible commentator, and payyeṭan. He is also known by the Hebrew name Tov Elem, a Hebrew translation from the French name "Bonfils." Of his life nothing is known but that he came from Narbonne, and was rabbi of Limoges in the province of Anjou. The ability and activity of Bonfils are best judged from his contributions to the poetry of the synagogue, no less than sixty-two of his piyyuṭim occupying prominent places in the French, German, and Polish liturgies. (Joseph Bonfils must not be confused, as he is by Azulai, with another scholar of the same name, who lived in 1200 and corresponded with Simḥah of Speyer (Responsa of Meïr ben Baruch of Rothenburg. ed. Cremona, No. 148).)
