Ambroise Janvier (1613, Sainte-Osmane â 25 April 1682, Saint-Germain-des-Prés) was a 17th-century French Benedictine and theologian.
He joined the Congregation of Saint Maur in 1657, and made great progress in the study of the Hebrew language which he taught for many years at the Abbey of Vendôme and elsewhere.
Dom Janvier was also publisher of the à Âuvres by Pierre de Celle, bishop of Chartres, Paris, 1671, in-4ð, with a preface of Father Jean Mabillon.
