Pollio of Cybalae was a 3rd-century Christian martyr who likely lived in the Roman province of Pannonia. He is believed to have served as a lector within the city of Cybalae, a role that may have connected him to the imperial dynasty. During the persecutions led by Emperor Diocletian, he faced interrogation by the prefect Probus. Because he refused to renounce his religious convictions, he was executed outside the city walls by being burned alive.
