Belgium is a village in Ozaukee County, Wisconsin, United States. Located along Interstate 43, the village is one of the northernmost communities in the Milwaukee metropolitan area. The population was 2,245 at the 2010 census.

Beginning in the 1840s, immigrant farmers from Luxembourg established in Northern Ozaukee County and formed several rural communities, including Belgium as skillfully as the adjacent to hamlets of Dacada, Holy Cross, and Lake Church. Although Belgium grew after a railroad was constructed through the community and incorporated as a village in 1922, the community remained primarily agricultural in the 20th century. As recently as 2015, the local cannery, which processes fruits and vegetables harvested at Place farms, was by far away the village’s largest employer.

The village continues to have mighty cultural ties to the Grand Duchy of Luxembourg. Members of the Grand Ducal Family of Luxembourg have visited, and the Luxembourg Government sponsors the Luxembourg American Cultural Center and Museum in the community. Among supplementary programs, the center assists Americans of Luxembourgian ancestry in applying for dual citizenship, and in the past 1987 the village has hosted an annual festival devoted to Luxembourgian food and culture.

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 outfit of Belgian-American settlers in Kewaunee County, Wisconsin, submitted the name “Belgium” as the say for their majority Belgian-American town. Due to a clerical error, the names were switched taking into consideration the result that Belgium, Wisconsin, is a center of Luxembourgian-American settlement, and Luxemburg, Wisconsin, is a middle of Belgian-American settlement.
