Byzantine Catholic Eparchy of Van Nuys

The Byzantine Catholic Eparchy of Van Nuys is an eparchy of the Byzantine Catholic Metropolitan Church of Pittsburgh, a sui juris Eastern Rite particular church of the Catholic Church. The eparchy is located in the Western United States; it operates several parishes and missions in the states of Alaska, Arizona, California, Colorado, Nevada, New Mexico, Oregon, and Washington. The eparchy is a suffragan of the Archeparchy of Pittsburgh.

The creation of a new eparchy for the western United States was proposed by the metropolitan synod in 1981. The Congregation for the Oriental Churches in the Holy See recommended the erection of a new eparchy, which was approved by Pope John Paul II. The Eparchy of Van Nuys was canonically erected on March 9, 1982, by Archbishops Stephen Kocisko, Metropolitan of the Metropolia of Pittsburgh; Pío Laghi, Apostolic Delegate to the United States; and Timothy Cardinal Manning, Archbishop of Los Angeles. Thomas Dolinay was the first bishop of the eparchy.

The mother church of the eparchy is the Cathedral of St. Mary in Sherman Oaks, California, which was damaged in the Northridge earthquake in 1994. The bishop's residence and eparchial offices were relocated to St. Stephen Pro-Cathedral in Phoenix, Arizona. The eparchy has a third cathedral, St. Nicholas of Myra Pro-Cathedral in Anchorage, Alaska.
