Wilco is a farmer-owned farm supply cooperative that began as the Santiam Farmers Co-op in the 1930s based in the Willamette Valley of the U.S. state of Oregon. In 1967, the Santiam Farmers Co-op merged with 4 other co-ops, the Mt. Angel Farmers Union Warehouse, the Donald Farmers Co-op, the Valley Farmers Co-op in Silverton, and the Canby Cooperative to form "Wilco Farmers Co-op". The name "Wilco" comes from a shortening of "Willamette Consolidated".
