Williamson County Fairgrounds
101 North Fair Street, Marion, IL 62959
Fairgrounds

The Williamson County Illinois Fairgrounds has hosted the longest running county fair for 161 years. The Fairgrounds is open all year round and is available for birthday parties, picnics and can hold most any event.
The Williamson County Fair continues to draw residents from all over Southern Illinois and afar. The grandstand events still thrill young and old alike, and the Saturday Championship Demo Derby is always sold out long before the first car takes to the track. Local residents bring their arts and crafts for cash prizes and of course bragging rights with the ribbons. Horsemen have enjoyed harness races on the same track for over a hundred-years and on the east end of the grounds western, gaited and speed horse shows are well attended.
