卡托利科斯（英语：Catholicos）是一个在部分东方基督教使用的头衔。此头衔用于一些东正教自治教会或是东方正统教会的领袖身上，通常会配合宗主教的头衔一并使用。而有些例子中这些头衔则会由一位宗主教赠与给一个他辖下的个别教会的领袖

有记录中最早使用这一头衔的应是亚美尼亚使徒教会的领袖。自从启蒙者额我略受命为亚美尼亚的主教后，这个头衔就跟着亚美尼亚使徒教会的历代领袖。

此外由于东方亚述教会的领袖也使用这个头衔的缘故也影响了许多与此相关的叙利亚礼教会，包括东仪天主教的加色丁礼天主教会等。

Catholicos, plural Catholicoi, is a title used for the head of certain churches in some Eastern Christian traditions. The title implies autocephaly and in some cases is borne by the designated head of an autonomous church, in which case the holder might have other titles such as Patriarch. In other cases a catholicos heads a Particular Church and is subject to a patriarch or other church head. The word comes from ancient Greek καθολικός, pl. καθολικοί, derived from καθ' ὅλου (kath'olou, "generally") from κατά (kata, "down") and ὅλος (holos, "whole"), meaning "concerning the whole, universal, general"; it originally designated a financial or civil office in the Roman Empire. The name of the Catholic Church comes from the same word.
