Louisiana was the name of an administrative district of New Spain from 1764 to 1803 that represented territory west of the Mississippi River basin, plus New Orleans, Louisiana. Spain acquired the territory from France: see Louisiana (New France).

The area, comprising what is now known as the Louisiana Purchase, was turned over to the French for a few days in 1803 before it, in turn, was turned over to the United States.

Spain was to be largely a benign absentee landlord administering it from Havana, Cuba and contracting out governing to people from many nationalities as long as they swore allegiance to Spain.

Although only maintaining it for 36 years, the Spanish were the ones who in fact were responsible for establishing much of New Orleans and Louisiana character that are normally associated with the French. Further, the Spanish control was to continue Catholic influence in the region.
