Thiensville is a village in Ozaukee County, Wisconsin, United States. Located on the west bank of a bend in the Milwaukee River, the community is bordered on all sides by the City of Mequon and is a suburb in the Milwaukee metropolitan area. The population was 3,235 at the 2010 census. Thiensville was the site of a Potawatomi village in the early 19th century before white settlers began arriving in the 1830s and 1840s. Many of the community's earliest settlers were German immigrants who were members of freethinker societies. One prominent freethinker was Joachim Heinrich Thien, for whom the village is named. Thien played a significant role in the Town of Mequon's early politics and organized the Thiensville Volunteer Fire Department. The freethinkers were opposed to organized religion and actively prevented churches from being established in the community for the first eight decades of its history. Thiensville grew and prospered in the late 1800s when it became a railway stop; the community became more urban with stores, mills and services for farmers in the rural Town of Mequon. The Village of Thiensville formally incorporated in 1910. Both Mequon and Thiensville experienced significant development during the suburbanization that followed World War II, with Mequon incorporating as a city in 1957. The two communities have close ties, with a shared chamber of commerce, library, and school district. In July 2005, CNNMoney.com ranked Thiensville and Mequon 19th on its list of the 100 Best Places to Live in the United States.
