John IV of Ohrid

Adrianos Komnenos (Greek: Ἀδριανός Κομνηνός; c. 1088 – 1163/64) was a Byzantine prince of the Komnenian dynasty, who became a monk and served as Archbishop of Ohrid as John IV (Ἰωάννης Δ΄) between 1139/42 and his death, sometime in 1163/64.

Few details about his life are known. As a younger nephew of the Byzantine emperor Alexios I Komnenos, he received a good education and military training. He went on to serve as governor of the province of Chaldia, where he distinguished himself by his good government, at least according to a celebratory piece written in his honour. He was married and had at least two daughters, but little is known of them or their offspring. Eventually he became a monk, under the name of John. In 1136–1138 he accompanied his cousin John II Komnenos on campaign, and went on to pilgrimage in the Holy Land. By 1142/43, he had been appointed as Archbishop of Ohrid, a position he maintained until his death in 1163/64. He was the first occupant of the office to use the title "Archbishop of Justiniana Prima and all Bulgaria", which later became the standard title of the see.
