About Dayton Fair

The Dayton Fair is a six-day mid-August fair in the rolling dairy country of Armstrong County, a community tradition in the Mahoning Creek valley east of Pittsburgh where small-scale farming persists in the forested Allegheny foothills.

What to Expect

Expect livestock shows, 4-H and FFA competitions, local food vendors, and the close-knit community atmosphere of a small western Pennsylvania township fair.

Visitor Tips

Dayton sits in Armstrong County near Kittanning on the Allegheny River — Parker Dam State Park, the Allegheny River canoe trail, and the Armstrong Trail through the river gorge are excellent nearby outdoor destinations.
