Grant County Fairgrounds About us
Trowbridge family The first Grant County Fair was held in October 1909 in John Day, Oregon on land that was donated by the Trowbridge family to the Agricultural Society for the purpose of holding a fair and race meet annually.

The original verbal agreement was formalized in 1962 when additional adjoining land was purchased from the Trowbridge family by the Grant County Court with the approval of the Grant County Fair Board. The fair is now the longest-running annual county fair in the state and is held annually on the fourth weekend in August.

The Fairgrounds complex is located inside the city limits of John Day, Oregon, just a few blocks north of the downtown area. John Day and Grant County are noted for their diverse outdoor recreational opportunities, including hiking, hunting, biking, fishing, snowmobiling and many other activities.

Local attractions like the Kam Wah Chung Museum, the Ranch & Rodeo Museum and Gleason Pool are within a short walking distance from the property. The Grant County Historical Museum is a little over a mile away and the Malheur National Forest hiking trails and the John Day Fossil Beds National Monument are within 30 to 45 minutes driving distance.


The mission ofthe Grant County Fairgrounds is to provide opportunities in a multi-purpose venue to ensure the citizens of Grant County can participate in a variety of educational, recreational, agricultural, commercial and social activities.
