Porphyrogénnētos, Latinized as Porphyrogenitus (, literally "born in the purple") was an honorific title given to a son, or daughter (Πορφυρογ?ννητη, Porphyrogénnētē, Latinized Porphyrogenita), of a reigning emperor in the Byzantine Empire. However, not every imperial prince or princess was accorded this distinction.
