What the Campbell County Fair Is
The Campbell County Fair in Gillette runs ten days, July 24 to August 2 in 2026. For 4-H and FFA families it is the main event of the summer: fabric and fashion judging, a style show, interview judging for static exhibits, a Cloverbud program for the youngest members, a horse show, livestock classes, and a youth livestock sale. A Wyoming State Fair entry meeting follows right after.
Who Can Enter
Youth must care for and exhibit their own animals, and fitting is by 4-H or FFA members only. Cloverbuds (the youngest 4-H members) have their own events. Fair entries and horse safety certifications were due July 1, and horse IDs were due June 1; unidentified horses cannot be entered.

Wyoming County Fairs: The Essentials
Wyoming county fairs run mostly from late July into early August, and most 4-H and FFA divisions are run through the county UW Extension office. In 2026, Park County opened July 21-25, Albany County ran July 22 to August 1, Laramie County ran July 29 to August 8 and the Wyoming State Fair in Douglas ran August 11-15.
Examples
Teton County's 2026 entries were due July 1 at 11:59 pm with no late entries. Niobrara County's 4-H and FFA entries closed July 10. Sweetwater County charged a $25 late fee in 2024. Teton counts interview judging as 40 percent of the exhibit score.
Livestock
Ownership deadlines of February 1 for market beef and June 1 for many other species are common. Laramie County requires YQCA for livestock projects, and Teton requires tagging photos. Tags, weigh-in, minimum weights and sale rules differ by county, so read your fair book early.
Sale and premiums
Teton members may sell one animal per species and no more than two in total, and a white ribbon cannot sell. Niobrara charges 3 percent commission and requires a thank-you note delivered to the Extension office before payment.
