About Winnebago County

Winnebago County is located in east-central Wisconsin, situated along the western and southern shores of Lake Winnebago, the largest inland lake in the state and one of the largest in the entire country. Covering approximately 465 square miles, the county encompasses a diverse landscape of lakefront communities, rolling farmland, wetlands, and small urban centers that together give it a distinctive character found nowhere else in the Midwest. The Fox River, which both feeds and drains Lake Winnebago, runs through the county and has historically shaped the settlement patterns and development of the region. Winnebago County's location along this natural water corridor has made it a geographic hub for travel, commerce, and recreation throughout its history. With a population of approximately 171,730 residents, Winnebago County is one of the more populous counties in Wisconsin, blending the character of a mid-sized metropolitan area with the close-knit feel of a Midwestern community. The county seat, Oshkosh, is the largest city and serves as the political, cultural, and economic center of the region. Oshkosh is perhaps best known internationally as the home of EAA AirVenture, one of the world's premier aviation events, drawing hundreds of thousands of visitors annually. Beyond Oshkosh, communities such as Neenah, Menasha, and Omro each contribute their own distinct identities to the broader county fabric. The economy of Winnebago County is varied and resilient, rooted in manufacturing, healthcare, education, and retail trade. Major employers include Oshkosh Corporation, a global manufacturer of specialty vehicles, along with ThedaCare health systems and the University of Wisconsin-Oshkosh. The county's position within the Fox Cities metropolitan area connects it to a broader regional economy that supports tens of thousands of jobs. Agriculture also remains a meaningful part of the local economy, with dairy farming and crop production contributing to the rural portions of the county. This mix of industry, education, and natural resources creates a stable and dynamic environment where residents build careers, raise families, and engage deeply with their community.
