We plan to kick up our heels in fine style on Father’s Day Weekend June 17-20, 2021.

Oswego’s four-day community celebration brought to you by the Oswegoland Park District, generous business sponsors, civic organizations, and hundreds of volunteers. We warmly invite you to be a part of “The Festival You Know By Heart”. Whether supporting the fest, hosting an event, or participating in the fun, there’s a place for you at your community festival. PrairieFest events are held throughout Oswego with the main festival grounds located at PrairieFest Park, 91 Plank Road, Oswego, IL.
