The first Clayton County Fair was held in Garnavillo, October 3, 1854. Just three weeks before the first Iowa State Fair was held.

In the early history of our great country, state of Iowa, and Clayton County, fairs have played an important part in the building of our great agricultural industries. Beginning in the 1920's to the present date, the 4-H and FFA organizations played an important part in the development of one of Iowa's best agricultural fairs.

Clayton County Fair now consists of about 30 acres (as of 2003), which gives Clayton County one of the larger fairgrounds in the state of Iowa.

We welcome all ages to the Clayton County Fair! Come join in on the fun!
