The Archbishopric of Athens is a Greek Orthodox archiepiscopal see based in the city of Athens, Greece. It is the senior see of Greece, and the seat of the autocephalous Church of Greece. Its incumbent is Ieronymos II of Athens. As the head of the Church of Greece, the holder is styled Archbishop of Athens and All Greece.

The Church of Greece, part of the wider Greek Orthodox Church, is one of the autocephalous churches which make up the communion of Eastern Orthodox Christianity. Its canonical territory is confined to the borders of Greece prior to the Balkan Wars of 1912–1913, with the rest of Greece being subject to the jurisdiction of the Ecumenical Patriarchate of Constantinople. However, most of the dioceses of the Metropolises of the New Lands are de facto administered as part of the Church of Greece for practical reasons, under an agreement between the churches of Athens and Constantinople. The primate of the Church of Greece is the archbishop of Athens and All Greece.
