Allen County Fair - August 15-23, 2025

We invite you to join us in celebrating the 175th Allen County Fair. Throughout the years, the fair has undergone a tremendous amount of infrastructure changes and expansion. We attribute this growth and success to the overwhelming community support we have received for 175 strong years. We look forward to sharing with you soon, all of the excitement, projects, and festivities that will be available for all ages to enjoy August 15th – 23rd 2025.
