Since 1856, the Big Butler Fair has been Butler County’s premier agricultural celebration and one of the most beloved county fairs in the tri-state region. As a 501(c) nonprofit organization, the fair is organized and operated entirely by dedicated volunteers committed to preserving Western Pennsylvania’s farming heritage while providing world-class family entertainment.
The Big Butler Fair is the largest agricultural fair in Western Pennsylvania. The event draws over 100,000 visitors from across Pennsylvania, Ohio, New York, and West Virginia to enjoy 9 days of fair food, fireworks, carnival rides, midway games, demolition derbies, live concerts, truck pulls, livestock competitions, and the Y108 Freedom Festival. The Big Butler Fair is considered by many to be the best county fair in the country.
From its humble 1856 beginnings at Kearns Crossing to its current home on New Castle Road in Prospect, PA, the Big Butler Fair has grown every year since its founding. Today, the fair occupies its largest space to date and is proud to bring entertainment ranging from local musicians to nationally recognized acts.
