Asterius, Claudius and Neon (Greek: Άστέριος, Κλαύδιος & Νεών) were a group of brothers who suffered martyrdom.

In summary, Christians could be put to death if they refused to give cult to the Roman state's patron deities as part of the Great Persecution of the early 300s AD.

The Romans attributed their success as a world power to their collective piety (pietas) in maintaining good relations with the gods.

Brothers Claudius, Asterius, and Neon were denounced to the magistrate of Ægea "by their mother-in-law, whose principal view was to possess herself of their estate."

The prisoners were presented to him one by one and offered "honours and rewards" if the Christians would sacrifice to the Roman gods, and he promised torture and death if they refused.
