Diocese of Cheyenne Menu

Welcome to the Diocese of Cheyenne website!

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.

Jubilee Year of Mercy

We need constantly to contemplate the mystery of mercy. It is a wellspring of joy, serenity, and peace. Our salvation depends on it. Mercy: the word reveals the very mystery of the Most Holy Trinity. Mercy: the ultimate and supreme act by which God comes to meet us. Mercy: the fundamental law that dwells in the heart of every person who looks sincerely into the eyes of his brothers and sisters on the path of life. Mercy: the bridge that connects God and man, opening our hearts to a hope of being loved forever despite our sinfulness. (Pope Francis, Misericordiae Vultus, 2)
