Wilco is a farm supply cooperative based in the Willamette Valley of the U.S. state of Oregon. It was started in 1967 with a merger of the Mt. Angel Farmers Union Warehouse, the Santiam Farmers Cooperative, the Donald Farmers Co-op, the Valley Farmers co-op in Silverton, and the Canby Cooperative. The name "Wilco" comes from a shortening of "Willamette Consolidated". The cooperatives headquarters are in Mt. Angel.
