The Union County Fair is held at the Union County Fairgrounds in Marysville, Ohio. Participation by a 4-H Member at the Union County Fair is optional. Youth and families who choose to participate must educate themselves about the rules and procedures which govern each exhibition. When you choose to become a fair exhibitor, you have moved beyond the realm of 4-H, and into the area governed by our Agricultural Society (Fair Board). (
