Auteuil (French pronunciation: [otœj] ⓘ) is the 61st and 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 neighborhood, it is known for its mainly Catholic and old-money heritage population.
