Moses ben Nachman (Hebrew: מֹשֶׁה בֶּן־נָחְמָן Mōše ben-Nāḥmān, "Moses, son of Nachman"; 1194–1270), commonly known as Nachmanides (; Greek: Ναχμανίδης Nakhmanídēs), and also referred to by the acronym Ramban (; רמב״ן) and by the contemporary nickname Bonastruc ça Porta (Catalan: [ˌbɔnəsˈtɾuk sə ˈpɔrtə]; literally "Mazel Tov near the Gate", see astruc), was a leading medieval Jewish scholar, Spanish rabbi, philosopher, physician, kabbalist, and biblical commentator. He was raised, studied, and lived for most of his life in Girona, Catalonia.
