Darigold, Inc. is an American dairyagricultural marketing cooperative. Headquartered in Seattle, Washington, it is owned by the over 500 dairy farm members of the Northwest Dairy Association (formerly the Northwest Dairymen's Association) located in Washington, Oregon, Idaho, Northern California, and Montana. The cooperative was founded in 1918 as the United Dairymen's Association, and it bought the Consolidated Dairy Products Company in 1930. A contest among dairy families produced the cooperative's brand name, "Darigold" in 1920. In 1999 the cooperative, in an effort to improve its marketing position, changed its name to Northwest Dairy Association, while changing the corporate name to WestFarm Foods. In 2006 the corporate name returned to Darigold. In 2010 the cooperative merged with the Montana dairy cooperative Country Classic. The co-op's annual sales are over $2.0 billion, and production is over 8,600,000,000 pounds (3.9×109 kg) of milk a year.
