Saint Anne-Marie Javouhey (November 10, 1779 – July 15, 1851) was a French nun who founded the Sisters of Saint Joseph of Cluny. She is venerated in the Roman Catholic Church. She is known as the Liberator of the Slaves in the New World, and as the mother of the town of Mana, French Guiana. When news of her death in 1851 reached the black population of French Guiana, there was general grief for "the mother of the blacks". The cause for her beatification was introduced on February 11, 1908 and she was beatified on October 15, 1950.
