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.
