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.

Mequon () is the largest city in Ozaukee County, in the U.S. state of Wisconsin, and the third-largest city in Wisconsin by land area. Located on Lake Michigan's western shore with significant commercial developments along Interstate 43, the community is a suburb in the Milwaukee metropolitan area. Despite being an incorporated city, approximately half of Mequon's land is undeveloped and agriculture plays a significant role in the local economy. At the time of the 2020 census the population was 25,142. When the first white settlers arrived in the 1830s, the Mequon area was inhabited by the Menominee, Potawatomi, and Sauk people. In the 1840s, German immigrants settled in the community, building farms and hydropowered mills along the Milwaukee River. Much of the community remained rural, while Thiensville developed as a market town along the local railway, providing services to the farmers. Thiensville incorporated as a village in 1910. Mequon remained rural in the early 20th century but experienced significant population growth during the suburbanization that followed World War II. The community incorporated as a city in 1957 to avoid annexation by the City of Milwaukee. The City of Mequon completely surrounds Thiensville, leading some residents to call Thiensville "Mequon's donut hole." The two municipalities have a close relationship, with a shared chamber of commerce, library, and school district. Lutheranism has played a significant role in Mequon since the community's early years. Some of the first German settlers were Old Lutherans who founded the Freistadt community—now a neighborhood in western Mequon—in 1839 and went on to form the first Lutheran congregation in Wisconsin. In the 21st century, there are more Lutheran churches in Mequon than churches of any other single denomination. Additionally, Mequon is home to two private Lutheran post-secondary institutions: Concordia University Wisconsin and Wisconsin Lutheran Seminary. In addition to having other Christian denominations, Mequon is also the northernmost of Milwaukee's suburbs to have a sizable Jewish community.
