John the Oxite or John Oxeites was the Greek Orthodox Patriarch of Antioch (as John IV or V) from c. 1089 until 1100, when he was exiled by Prince Bohemond I of Antioch. He fled to the Byzantine Empire and continued to govern those parts of the patriarchate that were under Byzantine rule. He was a prominent writer of religious texts, and reformer of religious and charitable foundations. John never returned to Antioch and after him new Greek Orthodox Patriarchs of Antioch were appointed in Constantinople, remaining there until it was possible to restore them in Antioch late in the 13th century.
