The Florida Parishes (, ), the eastern side of Mississippi River which is also known as the Northshore region or the Northlake region, are eight parishes in the southeastern part of the U.S. state of Louisiana, which were part of West Florida in the 18th and early 19th centuries. Unlike most of Louisiana, this region was not part of the 1803 Louisiana Purchase, as it had been under British and then Spanish control for the prior forty years. The parishes are East Baton Rouge, East Feliciana, Livingston, St. Helena, St. Tammany, Tangipahoa, Washington, and West Feliciana.
