French Island is a census-designated place (CDP) in La Crosse County, Wisconsin, United States. The population was 4,207 at the 2010 census.[2] It lies on an island of the same name, though they are not coextensive; a portion of the island is part of the city of La Crosse. All of the island is part of the La Crosse Metropolitan Statistical Area. French Island is part of the town of Campbell and contains all of its population, because the balance of Campbell is uninhabited.
French Island is located in western La Crosse County. It is surrounded by waterways connected to the Mississippi River: French Slough, French Lake, and Lake Onalaska to the west, and the Black River and Richmond Bay to the east. Two parts of the dam forming Lake Onalaska on the Mississippi connect to French Island: one at the head of French Lake, and the other impounding the Black River.
The neighborhood of West La Crosse is in the southern part of the CDP.
