Wyoming Stock Growers Association

The Wyoming Stock Growers Association (WSGA) is an American cattle organization that started in 1872 among Wyoming cattle ranchers to standardize and organize the cattle industry but quickly grew into a political force that has been called "the de facto territorial government" of Wyoming's organization into early statehood, and wielded great influence throughout the Western United States. The WSGA is active to this day.
