The Weld County Fair is an annual free event held the last week in July. Our fair is open to the public and boasts a variety of displays and contests. The fair gives the youth and adults of Weld County an opportunity to exhibit their skills in a wide variety of areas including agriculture, livestock, natural resources, engineering, consumer and family, fine arts, horticulture and family living.

The Fair is planned and presented by a volunteer board appointed by the Weld County Commissioners, along with the Weld County Fair Coordinator and Fair Secretary. Colorado State University Extension Agents serve as educational advisors to the fair.
