Belgium, Wisconsin, is a village in Ozaukee County along I-43 between Milwaukee and Sheboygan. It had a population of about 2350 people, largely of Luxembourgian ancestry. Wait...not Belgian, you say?

No, not Belgian. Here's why, according to Wikipedia.
Since its beginning, Belgium has had a large population of Luxembourgian Americans. In 1857, the immigrant settlers submitted the name "Luxembourg" to the U.S. Postal Service for review. At the same time, a group of Belgian-American settlers in Kewaunee County, Wisconsin, submitted the name "Belgium" as the name for their majority Belgian-American town. Due to a clerical error, the names were switched with the result that Belgium, Wisconsin, is a center of Luxembourgian-American settlement, and Luxemburg, Wisconsin, is a center of Belgian-American settlement.
