Auteuil (French pronunciation: [otœj]) is the westernmost quarter of Paris, France, located in the 16th arrondissement, on the Right Bank. It is adjacent to Passy to the northeast (administratively part of la Muette), Boulogne-Billancourt to the southwest, and the Bois de Boulogne to the northwest. A very discreet neighbourhood, it is known for its mainly catholic and old-money heritage population.
