Maurice Charles Pierre Langeron (3 January 1874, in Dijon – 27 June 1950, in Bourg-la-Reine) was a French mycologist, bryologist and paleobotanist.

He studied natural sciences at the Muséum national d'histoire naturelle in Paris. In 1930 he was named director of the department of mycology in the laboratory of parasitology at the faculty of medicine in Paris. Two years later, he became adjoint-director in the laboratory of parasitology at the École pratique des hautes études. In 1942 he was appointed director of research at the Centre national de la recherche scientifique (CNRS).^[1]

In 1933 he became a member of the Société de biologie. With Émile Brumpt and Maurice Neveu-Lemaire, he founded the journal Les Annales de Parasitologie humaine et comparée,^[1] now continued as Parasite. The dermatophyte:genus Langeronia (Vanbreus., 1950) is named after him.^[2]
