Île d'Orléans (French for "Isle of Orleans") was the historic name for the New Orleans area, in present-day Louisiana, U.S.A.. In 1762, France, anticipating that Great Britain would take Louisiana at the end of the French and Indian War, in the Treaty of Fontainebleau transferred to Spain all of Louisiana west of the Mississippi River, as well as a newly-defined area east of the Mississippi which included New Orleans, called the Isle of Orleans.
