Western Idaho Fair 2026

The Western Idaho Fair is the most attended event in the state, welcoming nearly 300,000 people over ten days each August. Located in the heart of the Treasure Valley, 85% of attendees come from Ada and Canyon counties, offering sponsors unrivaled reach into local households and communities.

The fair is a multigenerational experience featuring livestock shows, food vendors, free concerts, carnival rides, shopping, and dozens of interactive exhibits. From pig races and petting zoos to sky rides and garden stage performers, the Western Idaho Fair has something for everyone—especially families.

Sponsorships range from high-visibility naming rights (Expo Building, Stages, Barns) to activation-heavy day sponsorships, product giveaways, and branded promotions. Premium sponsors receive inclusion in web/social promotions, on-site banners, maps, ticket giveaways, and frequent live mentions.

For brands looking to authentically engage everyday consumers in a relaxed, festive, and high-footfall environment, the Western Idaho Fair is Idaho’s gold-standard opportunity.
