Boulder County Fair

9595 Nelson Road
Longmont, CO 80501


The Boulder County Fair, with its deep historic roots, is the oldest fair in the state of Colorado. Started by a group of prominent ranchers and farmers, the first fair in the Colorado Territory was held on October 12, 1869. The vision of these early pioneers was to create a community event which would celebrate the rich diversity of the area, and reflect the activities of its citizens through exhibits encouraging the county's basic economy.

145 years from its first historic step, the Boulder County Fair is still going strong, still focusing on family-oriented activities and events, our agricultural heritage and tradition, and showcasing the outstanding work and projects of its 4-H and FFA youth and the community at large. The fair remains one of just four non-profit county fairs in the State of Colorado, and with a record 100,000 attendees last year! It is poised for a historical celebration in 2009!

The spirit of the original pioneers continues on with a current board, staff and volunteers dedicated to positioning the Boulder County Fair for the next years!
