Metropolis of Kastoria

The Metropolis of Kastoria () is one of the metropolises of the New Lands in Greece that are within the jurisdiction of the Ecumenical Patriarchate of Constantinople but de facto are administered for practical reasons as part of the Church of Greece under an agreement between the churches of Athens and Constantinople.
Kastoria is also a Latin Catholic titular see, and in the early 20th century hosted a Bulgarian Orthodox bishopric.

In the early 20th century the town was the seat of a Bulgarian Orthodox bishopric with 2,224 families, 32 priests, and 22 churches.
