Johannes de Garlandia or John of Garland was a medieval grammarian and university teacher. His dates of birth and death are unknown, but he probably lived from about 1190 to about 1270. He was born in England, and studied at Oxford and then at the medieval University of Paris, where he was teaching by 1220. He lived and taught on the Left Bank at the Clos de Garlande, after which is named. This is the origin of the name by which he is usually known. The main facts of his life are stated in his long poem De triumphis ecclesiae ("On the triumphs of the Church").
