Originally named Foster, Stanfield is named after Sen. Robert N. Stanfield who purchased the area in 1903 from C.B. Wade of Pendleton for use as the headquarters of his extensive sheep and wool enterprises. Because of its proximity to the railroad, the site was used for shearing wool, holding sheep for shipping, and storing supplies for the operations in warehouses. (At one time, Sen. Stanfield and his brothers operated the largest sheep ranching operations in North America.),
With the development of the Furnish Ditch irrigation system serving the lands around Stanfield, Sen. Stanfield joined with Dr. Henry Waldo Coe of Portland in 1909 to subdivide the area and create the town of Stanfield. Sen. Stanfield got half of the lots created by the subdivision and Dr. Coe's development company got the other half.,
Dr. Coe began operating excursion trains to bring interested buyers to Stanfield to see the lots that were being offered for sale. The two story Stanfield ranch house was turned into a hotel to house the visitors. (Pictures of the Stanfield Hotel with a small crowd of "Columbia Land Co. Excursionists" and the excursion cars "spotted" on a spur at Stanfield are on file in the Stanfield Library.)
A bank building was built with an office in the back for Sen. Stanfield. A door allowed the Senator to come and go without going through the bank lobby. (The old bank building is now the office of the Stanfield Irrigation District.)
Sen. Stanfield donated a number of parcels for public purposes, including the site of the high school.
