The 16th arrondissement of Paris (also known as "Arrondissement de Passy") is one of the 20 arrondissements (administrative districts) of Paris, the capital city of France. It includes a concentration of museums between the Place du Trocadero and the Place d'Iéna.

Situated on the right bank of the River Seine, this arrondissement—which includes the mainly residential districts of Auteuil and Passy -- is home to a large number of diplomatic embassies and is also the location of the famous Avenue Foch, the widest street in Paris and home to many of the City's wealthy foreign residents.

With its ornate 19th century buildings, large avenues, prestigious schools and museums and various parks, the arrondissement has long been known as one of French high society's favorite places of residence (comparable to New York's Upper East Side or London's Chelsea & Kensington) to such an extent that the phrase "le 16e" (French pronunciation: [lə sɛzjɛm]) has been associated with great wealth in French popular culture. Indeed, the 16th arrondissement is France's 4th richest district for average household income, only fourth to the 8th, 7th and 6th arrondissements; with Neuilly-sur-Seine, they are collectively referred to as Paris Ouest: the most affluent and prestigious residential area in France.
