St. Peter's Church in the present-day North Side of Pittsburgh served as the cathedral of the Diocese of Allegheny from 1876 until 1889.[1]

The Diocese of Allegheny is a former Roman Catholic diocese of the United States (1876–1889). It is currently a Latin episcopal titular see. In Latin, the see is known as Dioecesis Alleghenensis.


The diocese was created on 11 January 1876 with territory split from the Diocese of Pittsburgh, as a fellow suffragan of the Metropolitan Archdiocese of Philadelphia.

Bishop Michael Domenec was appointed as its first ordinary.

When Bishop Domenec died on 29 July 1877, Bishop John Tuigg, who at that time was serving as Bishop of Pittsburgh, was appointed Apostolic Administrator.

On 1 July 1889, the see was suppressed as a residential diocese and its territory was reunited with the diocese of Pittsburgh.[2]

Former territory[edit]

At its creation, the Diocese of Allegheny covered eight counties and an area of 6,530 square miles (16,900 km2), leaving the Diocese of Pittsburgh with six counties and an area of 4,784 square miles (12,390 km2). Allegheny County was split unevenly between the two dioceses, with most of that county remaining in the Diocese of Pittsburgh.[3]

The Rev. Andrew Lambing, an early historian of the Catholic Diocese of Pittsburgh, described the boundary lines as follows:

The dividing line between the sees of Pittsburg and Allegheny started at the southern boundary of the State between Bedford and Somerset counties, and passed north till it reached Cambria, and thence west to Westmoreland. Passing along the eastern, southern, and western boundary of this county, it struck the Allegheny River, and passed down that stream and the Ohio to the western limits of Allegheny City. From that point it struck due north through Allegheny County to the southern boundary of Butler, and continued west and north to the line dividing Lawrence and Mercer counties. It then followed that line to the western boundary of the State.[4]
