Cephas is a proper noun used primarily as a given name or biblical proper noun. It is pronounced as two syllables with stress on the first: CHEE-fahs (often rendered as /ˈsiː.fəs/ in Greek-derived usage, though some pronunciations in English contexts render it closer to /ˈsiː.fæs/). The term historically refers to the apostle Peter in biblical translations, but in modern use it appears as a personal name in various cultures.
