The enduring character of religion in Wyoming is shaped by vast geographic distances and close-knit frontier communities. Over seventy percent of adult residents identify as Christian, led by Roman Catholic parishes, Latter-day Saint congregations in western valleys, and widespread Baptist and Lutheran churches that anchor the state's rural towns and ranching basins.
Demographic Profile: Religion in Wyoming Today
According to the 2014 Pew Research Center Religious Landscape Study, approximately 71 percent of adults in Wyoming identify as Christian. Evangelical Protestants form the largest collective tradition at roughly 27 percent, followed by mainline Protestants at 16 percent and Roman Catholics at 14 percent. Members of The Church of Jesus Christ of Latter-day Saints constitute approximately 9 percent of the adult population, maintaining a substantial presence that reaches over 20 percent in southwestern border counties. Non-Christian traditions represent roughly 3 percent of residents, while 26 percent identify as religiously unaffiliated, describing their outlook as atheist, agnostic, or nothing in particular.
The 2020 US Religion Census provides additional perspective on institutional adherence in the least populous state. In terms of participating adherents, the Roman Catholic Church and The Church of Jesus Christ of Latter-day Saints stand as the two largest religious bodies in Wyoming, each claiming between 55,000 and 65,000 adherents statewide. For newcomers investigating the most common religion in Wyoming, Christianity remains the overwhelming majority tradition, yet religious life is characterized by small, self-reliant congregations where neighbors of differing theological views regularly cooperate on civic initiatives.
Operating in a state with fewer than 600,000 residents spread across nearly 98,000 square miles creates distinct logistical conditions. Local churches in Wyoming frequently share pastors, maintain cooperative food ministries, and serve as central community meeting places in towns separated by dozens of miles of open prairie or mountain passes.

Trails, Rails, and Settlement: How History Formed Wyoming Faith
Long before European explorers traversed the Rocky Mountain West, Shoshone, Arapaho, Cheyenne, and Crow nations held sacred ceremonies across Wyoming, venerating sacred landscapes like Devils Tower (Bear's Lodge) and the Medicine Wheel in the Bighorn Mountains. Formal Christian presence began in the 1840s when tens of thousands of emigrants crossed the Continental Divide via South Pass along the Oregon, California, and Mormon trails. Jesuit missionary Father Pierre-Jean De Smet celebrated the first recorded Catholic Mass in Wyoming in 1840 near Daniel, while Mormon pioneer handcart companies established waystations in the Green River Valley.
The critical development occurred in 1867 and 1868 when the Union Pacific Railroad laid tracks across southern Wyoming, creating railhead towns almost overnight. Episcopal, Methodist, Presbyterian, and Catholic missionaries quickly followed the rails, establishing canvas-tent chapels that evolved into brick and stone sanctuaries. Coal mining in places like Rock Springs, Hanna, and Kemmerer attracted Irish, Italian, and Slavic miners who built Catholic parishes. Simultaneously, Latter-day Saint pioneers established agricultural colonies in the Star Valley, the Bridger Valley, and the Bighorn Basin, establishing a permanent religious presence that remains vital today.
Historic Chapels and Spiritual Landmarks of the High Plains
Wyoming preserves several of the most striking and picturesque religious sites in the American West:

- Star Valley Wyoming Temple, Afton: Dedicated in 2016, this elegant temple serves Latter-day Saints across western Wyoming and eastern Idaho, representing the deep historical roots of pioneer families in the Salt River Valley.
Urban Centers: Where Wyoming Congregations Gather
Because Wyoming is predominantly rural, church facilities are concentrated in its two largest population centers and key highway junctures. The state capital leads our directory with churches in Cheyenne, Wyoming, recording 26 listings. Cheyenne features historic downtown pulpits, military base ministries near F.E. Warren Air Force Base, and suburban congregations serving growing residential neighborhoods.
In the central portion of the state, churches in Casper, Wyoming account for 23 listings. Known as the Oil City, Casper hosts a broad array of active Catholic, Baptist, Lutheran, and non-denominational congregations that provide regional leadership throughout Natrona County. At the eastern agricultural edge of the high plains, churches in Pine Bluffs, Wyoming represent rural farming communities where single church facilities often serve as central gathering places for farm families spanning several counties.
Wyoming and Its Surrounding Neighbors
Understanding faith in Wyoming requires looking at surrounding mountain and plains states. As discussed in our overview of religion in the West, Wyoming occupies an intriguing crossroads between the Great Plains and the Intermountain West.
To the north, our study of religion in Montana reveals shared challenges of vast rural distances and low population density, with Catholic and Lutheran traditions anchoring ranching towns. To the east, crossing into the agricultural heartland, our guides to religion in South Dakota and religion in Nebraska show significantly higher rates of formal church membership, driven by deep Lutheran and Catholic heritage in the farming belt. To the west, the cultural influence of Utah is immediately felt in southwestern Wyoming counties, where Latter-day Saint ward chapels and seminary buildings match those of neighboring states. Wyoming remains a compelling example of frontier faith, where community cooperation overcomes vast geographic distances.
