The Church of Cyprus is one of the autocephalous Greek Orthodox churches that together with other Eastern Orthodox churches form the communion of the Eastern Orthodox Church. It is one of the oldest Eastern Orthodox autocephalous churches; it claims to have always been independent, although it may have been subject to the Church of Antioch before its autocephaly was recognized in 431 at the Council of Ephesus. The bishop of the ancient capital, Salamis was constituted metropolitan by Emperor Zeno, with the title archbishop.

Greek Cypriots are the ethnic Greek population of Cyprus, forming the island's largest ethnolinguistic community. According to the 2011 census, 659,115 respondents recorded their ethnicity as Greek, forming almost 99% of the 667,398 Cypriot citizens and over 78% of the 840,407 total residents of the area controlled by the Republic of Cyprus. These figures do not include the 29,321 citizens of Greece residing in Cyprus, ethnic Greeks recorded as citizens of other countries, or the population of Northern Cyprus.
