The Société de Linguistique de Paris (established 1864) is the editing body of the BSL (Bulletin de la Société de Linguistique) journal on linguistics, which contains the proceedings of the society's seven yearly discussion sessions.
Each January, the group holds a study day dedicated to a particular topic. In 1997, it organised the Congrès International des Linguistes in Paris.
