The Abbey of Saint-Sauveur-le-Vicomte, located in the commune of Saint-Sauveur-le-Vicomte in the Manche department of France, was a Benedictine monastery founded in the 11th century by Néel de Néhou, Vicomte of Saint-Sauveur. The abbey has longstanding connections with the nearby Channel Islands. After being dissolved in the French Revolution it became in the 1830s the mother house of the Sisters of Christian Schools of Mercy, now the Congregation of Saint Marie-Madeleine Postel.
