The city of Anazarbus was an archdiocese of the Syriac Orthodox Church, attested between the sixth and twelfth centuries. Nearly thirty Syriac Orthodox bishops or metropolitans of Anazarbus are mentioned either by Michael the Syrian or in other Syriac Orthodox narrative sources. The archdiocese is last mentioned towards the end of the twelfth century, and seems to have lapsed in the early decades of the thirteenth century. Sources The main primary source for the Syriac Orthodox metropolitans of Anazarbus is the record of episcopal consecrations appended to Volume III of the Chronicle of the Syriac Orthodox patriarch Michael the Syrian (1166–99). In this Appendix Michael listed most of the bishops consecrated by the Syriac Orthodox patriarchs of Antioch between the ninth and twelfth centuries. Twenty-eight Syriac Orthodox patriarchs sat during this period, and in many cases Michael was able to list the names of the bishops consecrated during their reigns, their monasteries of origin, and the place where they were consecrated. For the sixth and seventh centuries, Michael's lists are supplemented by several references in other Syriac Orthodox narrative sources.

Eighth- to twelfth-century bishops Twenty-five Syriac Orthodox metropolitans of Anazarbus from the end of the eighth century to the end of the twelfth century are mentioned in the lists of Michael the Syrian.
