Statistics and extent
As per 2014, it pastorally served 291,000 Catholics (10.0% of 2,900,872 total) on 219,887 km² in 48 parishes with 69 priests (62 diocesan, 7 religious), 75 deacons, 43 lay religious (14 brothers, 29 sisters) and 7 seminarians. 
It comprises the entire state of Utah. Also known as the Utah Catholic Church or the See of Salt Lake City.
In 1871 Fr. Patrick Walsh built the first Catholic Church in Utah, dedicating it to St. Mary Magdalene. Father (later Bishop) Lawrence Scanlan arrived in 1873 to become pastor. He took care of the Catholic military men, immigrant miners and railroad workers who numbered in the hundreds. Small churches, schools, an orphanage and a hospital were built, staffed by clergy and by the Sisters of the Holy Cross, to serve the growing Catholic population. As the nineteenth century came to a close, the Catholic community in Salt Lake City was rapidly outgrowing the small church of St. Mary Magdalene.
- In 1887 the Church in Utah became the Apostolic Vicariate of Utah, on territory split off from its Metropolitan, the Archdiocese of San Francisco, entitle to a titular bishop. Bishop Lawrence Scanlan was the first Catholic bishop of Utah. Ground was broken for the new church in 1899. Construction for the Cathedral of the Madeleine would last nearly a decade, costing a small fortune for the estimated 3,000 Catholics in Utah at the turn of the century. Assistance was obtained from Catholic Mission Societies.
- On 1891.01.27 it was promoted as the Diocese of Salt Lake / Lacus Salsi (Latin).
On 1931.03.27 it lost territory to establish the Diocese of Reno, in the same province.
On 1951.03.31 it was renamed as Diocese of Salt Lake City / Civitatis Lacus Salsi (Latin)
