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.

Living and Giving in Christ

Your gifts help gather young adults together from across the Diocese to reflect on the tasks that lead them to a personal relationship with Christ.

Your generosity assists in building strong Catholic families, promotes prayer for vocations and encourages young people to pursue the call to religious life.

Your light helps so many see that all we have and all we are is a gift from God, and helps us know God can never be outdone in generosity.

Your help promotes the full, active participation of God’s people in the transforming and redeeming work of Christ in the liturgy and sacraments.

Your support invites all people in the Diocese of Cheyenne to “come and see,” so we can all strengthen our relationships with Jesus Christ.

Your love nurtures life-long faith formation experiences for all people in the Diocese of Cheyenne through well-trained parish catechists.

We are truly blessed to have been given so much here in the Diocese of Cheyenne. But there is always more we can do. There are so many hearts, minds and souls we can touch with God’s love.

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)
