Armenian Catholic Archeparchy of Lviv, Catholic Archieparchy in Lviv, Ukraine

The Armenian Catholic Archeparchy of Lviv was an Eastern Catholic archdiocese of the Armenian Rite, founded in 1630 and vacant since the Second World War. It was immediately dependent on the Armenian Catholic Patriarch of Cilicia rather than part of any ecclesiastical province. Its archiepiscopal see was the Armenian Cathedral of the Assumption of Mary in Lviv, now an Armenian Apostolic church.

The archeparchy was erected on 24 October 1630 with Mikołaj Torosowicz as its first archeparch, on territory that had previously lacked an ordinary of the Armenian Rite. It remained immediately subject to the Armenian Catholic Patriarch of Cilicia rather than part of any ecclesiastical province. It has been vacant since World War II, and its faithful are now also served by the Armenian Catholic Ordinariate of Eastern Europe.

The archeparchy followed the Armenian Rite, and its archbishops bore Armenian and Polish names in turn, from Mikołaj Torosowicz in 1630 to Józef Teodorowicz, who led it from 1901 until his death in 1938. The last to hold office was Apostolic Administrator Dionizy Kajetanowicz, from 1938 to 1944. The see has stood vacant since the Second World War.

The archeparchy has had no residential archbishop since 1944, so there is no see to visit; its former cathedral, the Armenian Cathedral of the Assumption of Mary in Lviv, now belongs to the Armenian Apostolic Church. Armenian Catholics in Ukraine are served instead by the Armenian Catholic Ordinariate of Eastern Europe.

The archeparchy's first ordinary, Mikołaj Torosowicz, was appointed on 24 October 1630 and led it until his death in 1681. Its last resident leader was Father Dionizy Kajetanowicz, who served as apostolic administrator from 1938 to 1944, when the see fell vacant.
