Wyoming’s counties trace their origins to the territorial era before statehood in 1890, when five original counties—Laramie, Carbon, Albany, Sweetwater (originally Carter), and Uinta—were created to ensure the peace, safety, and well-being of their communities. As the territory grew and evolved into a state, the number of counties expanded to twenty-three, each serving as a vital arm of state government at the local level. Together, these counties have long upheld the foundational role of local governance in maintaining Wyoming’s economic vitality, public safety, and quality of life.

Formed in 1976, the Wyoming County Commissioners Association (WCCA) unites all 23 counties under a shared mission to strengthen local government through networking, education, and unified action. Owned and governed by Wyoming’s county commissioners, WCCA represents the collective voice of counties before state and federal policymakers, fostering cooperation on critical issues such as land management, taxation, natural resources, and infrastructure. Guided by a vision of integrity, inclusion, and service, the Association equips local leaders with the tools and information they need to preserve the character and values that define Wyoming—ensuring that county governments remain strong, connected, and closest to the people they serve.
