Diocese of Cheyenne Menu

Welcome to the Diocese of Cheyenne website!

The Diocese of Cheyenne encompasses the entire State of Wyoming, to include Yellowstone and Grand Teton National Parks. 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.

See of Cheyenne Bishop status

Following the installation Mass of Archbishop Etienne as the fourth Archbishop of Anchorage Alaska, the See of Cheyenne is now vacant.
The College of Consultors has announced that Rev. Carl Gallinger has been named the Diocesan Administrator until a new Bishop of Cheyenne is named.
Until a new bishop is installed, no bishop is mentioned during the Eucharistic prayer. This symbolizes the great anticipation with which the People of God in the Catholic Church in Wyoming await their next shepherd.
