The jurisdiction of the eparchy extends to all Maronite Catholic faithful living in Argentina. Its eparchial seat is the Argentine capital,
Buenos Aires, where is located the Saint Maron Cathedral. It is not exempt, nor a hierarchical part of the Maronite patriarchal ecclesiastical structure, but a
suffragan see in the
ecclesiastical province of the Roman Rite Metropolitan
Archdiocese of Buenos Aires in Argentina, like its Ukrainian Catholic counterpart, the Eparchy
Santa María del Patrocinio en Buenos Aires. The Christians of this diocese are mostly
emigrants and are originally from
Lebanon. Their naming is originated from Saint
Maron the founder of the Maronite Church. The Eparchy of Saint Charbel of Buenos Aires counted some 750,000 Lebanese Maronite Catholics of prevalent
Arab Christian origin in 2010 and there were four parishes. ==Episcopal ordinaries==
