{{italic title}} The '''''Clavis Patrum Graecorum''''' ('[[Glossary|Key (Glossary)]] of the [[Greek Fathers]]') is a series of volumes published by [[Brepols]] of [[Turnhout]] in [[Belgium]]. The series aims to contain a list of all the [[Church Fathers|Fathers of the Church]] who wrote in [[Greek language|Greek]] from the 1st to the 8th centuries. For each author it lists all their works, whether genuine or not, extant or not. Each work is assigned a number. The CPG number is widely used as a reference in [[scholarly literature]]. The text itself is written in [[Latin]].
A corresponding [[Clavis Patrum Latinorum]] also exists for the Latin Fathers.
The two were created in order to facilitate publishing the [[Corpus Christianorum]] series of Latin and Greek texts.
