About St. Louis County Fair

The St. Louis County Fair in Clayton celebrates Missouri's most populous county — St. Louis County surrounds the independent city of St. Louis and contains most of the metropolitan area's population, from the storied suburbs of Ladue and Webster Groves to the diverse communities of north and south county. The county's agricultural heritage lives on at fairgrounds that honor farming roots in an overwhelmingly suburban landscape. The area's broader history includes notable events and landmarks dating to 1904.

What to Expect

Expect livestock shows, 4-H and FFA competitions, carnival rides, live entertainment, local food vendors, and a large, diverse fair drawing from one of Missouri's most populous and economically significant counties.

Visitor Tips

Clayton is an upscale county seat city with a thriving downtown. The Saint Louis Zoo (free admission), Forest Park (site of the 1904 World's Fair), the Saint Louis Art Museum, and the Gateway Arch National Park in adjacent St. Louis City define the region's extraordinary cultural landscape.
