Laramie County Events organizes the Laramie County Fair, an annual celebration of agriculture, youth achievement, and community in Cheyenne, Wyoming. Held at the Event Center at Archer, the fair is described as Wyoming’s largest county fair and brings together visitors for livestock shows, rodeos, agricultural exhibits, food vendors, midway attractions, and family entertainment. The 2027 fair is scheduled for August 4–14.

The organization supports local 4-H and FFA participants through the Youth Livestock Sale, where businesses and community members can purchase animals or contribute add-on support. Fairgoers can also take part in community contests, attend youth rodeo events, explore daily activities, and visit the Cheyenne Farmers Market. The fair provides resources for guests and exhibitors, including schedules, maps, competition information, and vendor applications, as well as camping registration and sponsorship opportunities. Many activities, including the midway and select rodeo events, are free to attend. Laramie County Events is based at the Event Center at Archer, a multipurpose venue with substantial event and prefunction space.
