Cappadocian Greeks, also known as Greek Cappadocians or simply Cappadocians, are an ethnic Greek community native to the geographical region of Cappadocia in central-eastern Anatolia; roughly the Nevşehir and Kayseri provinces, and their surroundings, in modern-day Turkey. There had been a continuous Greek presence in Cappadocia since antiquity, and the indigenous populations of Cappadocia, some of whose Indo-European languages may have been closely related to Greek, became entirely Greek-speaking by at least the 5th century.

Derinkuyu also known as Elengubu, Cappadocian Greek: Μαλακοπή Malakopi; Turkish: Derinkuyu Yeraltı Şehri) is an ancient multi-level underground city near the modern town of Derinkuyu in Nevşehir Province, Turkey, extending to a depth of approximately 85 metres (280 ft). It is large enough to have sheltered as many as 20,000 people together with their livestock and food stores. It is the largest excavated underground city in Turkey and is one of several underground complexes found throughout Cappadocia.
