Union County Fair

The Union County Fair is fun for the whole family! We strive to bring an event filled with entertainment, agriculture, education, arts and crafts, and community togetherness. We are grateful for the hard work and dedication of the OSU Extension Office, 4-H & FFA advisors and youth, Junior Fairboard and the Jr. Fair Livestock Committee.

In addition to the fair, the Union County fairgrounds hosts community events, entertainment, horse shows, 4-H events, and much more!
