History and Governance
The origins of Teton County date back to the early 20th century. It was officially authorized on February 15, 1921, and organized in 1922, having been carved out of a portion of Lincoln County. The creation of the county was necessitated by the distance residents had to travel to reach the previous county seat in Kemmerer. Because the area initially lacked the population and wealth required by standard regulations, a special act of the Wyoming Legislature was required to establish it. The county was named in honor of the Teton Range.
