This is a list of the colonial governors of Louisiana, from the founding of the first settlement by the French in 1699 to the territory's acquisition by the United States in 1803. The French and Spanish governors administered a territory which was much larger than the modern U.S. state of Louisiana, comprising Louisiana (New France) and Louisiana (New Spain), respectively. As part of the Third Treaty of San Ildefonso (1800), Spain retroceded Louisiana to the French Republic, but Spain continued to administer the territory until 1803 when French officials arrived shortly before the sale of Louisiana to the United States. At the same time, there are parts of present-day Louisiana which were historically administered by other European powers, with the most prominent example being the area known as the Florida Parishes, north of Lake Pontchartrain and east of the Mississippi River. This territory was originally part of French Louisiana, but it was administered by the Kingdom of Great Britain from 1763 to 1783, following the British victory in the French and Indian War, and then by Spain from 1783 until the West Florida Revolt in 1810.
