Normandy is a geographical and cultural region in northwestern Europe, roughly coextensive with the historical Duchy of Normandy.
Normandy comprises mainland Normandy (a part of France) and insular Normandy (mostly the British Channel Islands). It covers 30,627 square kilometres (11,825 sq mi). Its population in 2017 was 3,499,280. The inhabitants of Normandy are known as Normans; the region is the historic homeland of the Norman language. Large settlements include Rouen, Caen, Le Havre and Cherbourg.
The cultural region of Normandy is roughly similar to the historical Duchy of Normandy, which includes small areas now part of the departments of Mayenne and Sarthe.
