Sponsors & Partners

​

Events Held Throughout the Year combine to expose sponsors or advertisers to more than 300,000 people!

The Winnebago County Fair Association is a non-profit organization that relies on the support it receives from sponsors and advertisers.

​

Our mission is to provide a well-maintained facility for the children of 4-H during the fair, as well as for everyone else throughout the year. We also strive to make available a community entertainment venue that provides the opportunity for groups and organizations to be recognized. The fairgrounds are shared by all in the community, and we hope at one time or another, you have attended or participated in activities at the fairgrounds.

If you are interested in becoming a sponsor, please call the Fairgrounds office at 815-239-1641.
 

We would like to thank the following sponsors and advertisers for their contributions to the 2026 Fair.  Without them, we would not be able to accomplish our goals!
