Seal of the state of Wyoming, USA

Wyoming (/waɪˈoʊmɪŋ/ wye-OH-ming) is a landlocked state in the Mountain West subregion of the Western United States. It borders Montana to the north and northwest, South Dakota and Nebraska to the east, Idaho to the west, Utah to the southwest, and Colorado to the south. With an estimated population of 587,618 as of 2024, Wyoming is the least populous state despite being the tenth-largest by area, and it has the second-lowest population density after Alaska. The state capital and most populous city is Cheyenne, which had a population of 65,132 in 2020. Wyoming's western half consists mostly of the ranges and rangelands of the Rocky Mountains; its eastern half consists of high-elevation prairie, and is referred to as the High Plains. Wyoming's climate is semi-arid in some parts and continental in others, making it drier and windier overall than other states, with greater temperature extremes. The federal government owns just under half of Wyoming's land, generally protecting it for public use. The state ranks sixth in the amount of land—and fifth in the proportion of its land—that is owned by the federal government. Its federal lands include two national parks (Grand Teton and Yellowstone), two national recreation areas, two national monuments, and several national forests, as well as historic sites, fish hatcheries, and wildlife refuges. Indigenous peoples have inhabited the region for thousands of years. Historic and currently federally recognised tribes include the Arapaho, Crow, Lakota, and Shoshone. Part of the land that became Wyoming came under American sovereignty via the Louisiana Purchase, part via the Oregon Treaty, and, lastly, via the Mexican Cession. With the opening of the Oregon Trail, the Mormon Trail, and the California Trail, vast numbers of pioneers travelled through parts of the state that had once been traversed mainly by fur trappers, and this spurred the establishment of forts, such as Fort Laramie, that today serve as population centres. The Transcontinental Railroad supplanted the wagon trails in 1867 with a route through southern Wyoming, bringing new settlers and the establishment of founding towns, including the state capital of Cheyenne. On July 10, 1890, Wyoming became the union's 44th state. The Republican presidential nominee has carried the state in every election since 1968. Wyoming was the first state to allow women the right to vote doing so since it was territory in 1869, and achieving statehood in 1890. It was also the first state to grant women the right to assume elected office, as well as the first state to elect a female governor, Nellie Tayloe Ross. In honour of this part of its history, its official nickname is "The Equality State" and its official state motto is "Equal Rights". Farming and ranching, and the attendant range wars, feature prominently in the state's history. Wyoming's economy is largely based on tourism and the extraction of minerals such as coal, natural gas, oil, and trona. Its agricultural commodities include barley, hay, livestock, sugar beets, wheat, and wool. Wyoming does not require the beneficial owners of LLCs to be disclosed in the filing, which creates an opportunity for a tax haven. Wyoming levies no individual or corporate income tax and no tax on retirement income.
