The Place d’Acadie is a public square in the 6th arrondissement of Paris, dedicated on 8 March 1984 by the mayor of Paris, Jacques Chirac, and by the president of an association called "Les Amitiés Acadiennes", Philippe Rossillon.

The square takes its name from the old French North-American territory of Acadia that was once part of New France.

Acadia existed in what is now called New Brunswick and Nova Scotia, provinces of Canada that are, today, home to a large number of francophone Canadians.

Acadia is represented, in international forums on the French-speaking world's culture (francophonie), by the Province of New Brunswick.

Dedication of this square in Paris was meant to mark the hundredth anniversary of the Acadian flag in 1884 in connection with the second National Acadian Convention.
