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.
