The Whiteside County Fair returns to Morrison, Illinois, Aug. 18–22, 2026, at the Whiteside County Fairgrounds. This classic county fair brings together agriculture, entertainment, food, family activities, and small-town tradition for several days of summer fun.

Visitors can expect many of the familiar fair favorites, including livestock shows, exhibits, fair food, carnival-style attractions, grandstand events, and opportunities to celebrate the people, projects, and traditions that make Whiteside County special. One feature that sets the Whiteside County Fair apart from many other area fairs is its harness horse racing, a longtime fair tradition that continues to draw spectators each year.

While the full 2026 schedule has not yet been released, guests can expect a variety of activities and entertainment throughout fair week. Visitors are encouraged to check the Whiteside County Fair website and Facebook page closer to the event for updated schedules, admission details, racing information, grandstand entertainment, and daily fair activities.
