The Diocese of Cheyenne encompasses the entire State of Wyoming, to include Yellowstone National Park. The rich history of Catholicism in Wyoming began on July 5, 1840, when Father Pierre-Jean DeSmet said the first Catholic Mass near Horse Creek, at the Green River Rendezvous, in present-day Sublette County. Since then, with our Diocese established in 1887, we have grown to 33 parishes and missions. Our state is a land of wide open spaces and sparsely populated towns, but our people are faith-filled and tightly-knit, bound together by a love of God, country, community, and a Western spirit unique to this special place.
We invite you to explore our website and learn more about our Diocese. You will find quick links below to several of the more frequently visited pages within our site. Get to know our clergy, Diocesan officials, upcoming events and retreats, and even the history of our Diocese. All this and more can be found in the main menu at the top of the page.

“For as in one body we have many parts, and all the parts do not have the same function, so we, though many, are one body in Christ and individually parts of one another.”
