Normandy is a city in St. Louis County, Missouri, United States. The population was 5,153 at the 2000 census.
The town is on land once owned by Charles Lucas. Lucas obtained property from the Federal Government with land grants and he purchased the land from victims of the New Madrid Earthquake of 1811. He named it for the French coastal community of Normandy from which his father John Baptiste Charles Lucas came. His home was on the property of Incarnate Word Academy.
Lucas was to fight two duels on Bloody Island with Thomas Hart Benton and died in the 1817 duel.
