Edward Alexander Partridge was a Canadian teacher, farmer, agrarian radical, businessman and author. He was born in Ontario but moved to Saskatchewan where he taught and then became a farmer. He was active in the Territorial Grain Growers' Association (TGGA), founded in 1902, which addressed various problems with the Western Canada grain market. He founded the cooperative Grain Growers' Grain Company, the predecessor of the United Grain Growers, and the Grain Growers' Guide, a widely distributed weekly paper. His "Partridge Plan" was a broad and visionary proposal for addressing a wide range of farmers' issues, eliminating many abuses caused by the near-monopoly of grain elevator companies, and resulted in important reforms by the provincial governments. Patridge was named a National Historic Person in 2018.

The Territorial Grain Growers' Association (TGGA) was a farmer's association that was active in Western Canada at the start of the 20th century, in what was then the Northwest Territories and later became Saskatchewan and Alberta. It provided a voice for farmers in their struggle with grain dealers and the railways, and was influential in obtaining favorable legislation. After Alberta and Saskatchewan became provinces the TGGA was succeeded by the Alberta Farmers' Association and the Saskatchewan Grain Growers' Association.
