About Ottawa County Free Fair

The Ottawa County Free Fair in Miami is an August fair in the Tri-State mineral district of the far northeast corner of Oklahoma, celebrating the lead and zinc mining, cattle, and Quapaw and Cherokee tribal heritage of a county at the junction of Oklahoma, Kansas, and Missouri along the Neosho River. The area's broader history includes notable events and landmarks dating to 1929.

What to Expect

Expect livestock shows, FFA and 4-H competitions, local food vendors, and a fair in the rolling tallgrass prairie and former lead-zinc mining country of the Ozark border.

Visitor Tips

Miami is the Ottawa County seat — the Dobson Museum and the Coleman Theatre Beautiful (a 1929 Fox Deluxe venue on the National Register of Historic Places) preserve the heritage of this once-booming mining district, and the Tar Creek Superfund site (a legacy of the lead-zinc mines) is an important environmental history lesson in this corner of the old Quapaw Agency.
