Adrian of Batanea was a Christian martyr who lived during the early fourth century. Originally from Adria, he traveled to Caesarea Maritima to provide spiritual care to the local Christian community. Accompanied by Eubulus, he was arrested by guards acting under the orders of Governor Firmilian after declaring their religious purpose. His death occurred during a period of prolonged persecution in the region, marking him as one of the final martyrs of a twelve-year era of conflict in Caesarea.
