Waukesha County Fair

Join us for the 2026 Waukesha County Fair, Wisconsin’s oldest county fair (dating back to 1842) and the largest event in Waukesha County. Held over five fun-filled days each July, this family-friendly tradition celebrates our rural roots with barnyard animals, farm displays, crafts, delicious fair food and a thrilling midway. Organized by a non-profit volunteer team committed to supporting youth education through 4-H and FFA projects, the fair also features action-packed highlights like the Junior Livestock Auction, tractor pulls, classic car shows and more. Whether you’re planning a summer outing or simply looking to kick up your heels, the Waukesha County Fair offers something for every age—don’t miss it!
