The Byzantine Catholic Metropolis of Pittsburgh (Latin: Pittsburgensis ritus byzantini) is a metropolitan province for Eastern Catholics of the Byzantine Rite in the United States of America, with specific jurisdiction over several communities that originated (in terms of their ancestry) from the regions of Carpathian Ruthenia, Slovakia, Hungary and former Yugoslavia. Its membership thus includes several Byzantine Catholic groups, mainly among Rusyn Americans, Slovak Americans, Hungarian Americans, and Croatian Americans. Since 2022, the Exarchate of Saints Cyril and Methodius of Toronto in Canada has also been under the provincial jurisdiction the Metropolis of Pittsburgh rather than the Slovak Greek Catholic Church.
