Alameda County Fairgrounds

The Alameda County Agricultural Fair Association operates the Alameda County Fair. We are a private, non-profit corporation, and we are responsible for producing the annual Fair as well as other select events.

Other events during the year are produced by outside promoters who rent our facilities. The Alameda County Fair Association staff supervises all events. The Association is completely self-supporting, and receives no funding from tax revenue.

The Alameda County Fair originated in 1859 as a Floral Fair. The first modern-day Fair was held in 1939, and has been held annually with the exception of the war years.

The Alameda County Fair racetrack is the oldest one-mile horse racing track in America, dating back to 1858. The sons of Spanish Don Augustin Bernal constructed it, and wealthy horse owners shipped their horses from the east to Pleasanton for training during the winter months.
