While established in 1855, the first Butler Fair was held in 1856 on a plot of land east of the city near Kearns Crossing. The Big Butler Fair is the largest fair in Western Pennsylvania considered by many to be the best fair in the country. We are proud to be a symbol of American family values. Year after year, families from all over PA, OH, NY WV come to The fair to enjoy fireworks, the midway, games, demolition derbies, concerts truck pulls. It is always held over the 4th of July!
