This fair is an annual event for families and friends who like concerts, rides, animals and everything fair! Our fair is in the middle of June each year, ending on Father's Day. The Sangamon County Fair is a great way to start off the summer. It's a great Midwestern traditional fair with a tremendous talent lineup for the grandstand! This year, experience Grammy award winning artist Nelly on Thursday, June 17, and Riley Green on Friday the 18th. With so much food, drinks and fun you're bound to have a blast at the Sangamon County Fair.
