The Greeks in Turkey (Turkish: Rumlar) constitute a population of Greek and Greek-speaking Eastern Orthodox Christians who mostly live in Istanbul, including its district Princes' Islands, as well as on the two islands of the western entrance to the Dardanelles: Imbros and Tenedos (Turkish: Gökçeada and Bozcaada).

They are the remnants of the estimated 200,000 Greeks who were permitted under the provisions of the Treaty of Lausanne to remain in Turkey following the 1923 population exchange, which involved the forcible resettlement of approximately 1.5 million Greeks from Anatolia and East Thrace and of half a million Turks from all of Greece except for Western Thrace. After years of persecution (e.g. the Varlık Vergisi and the Istanbul Pogrom), emigration of ethnic Greeks from the Istanbul region greatly accelerated, reducing the 119.822 -strong Greek minority before the attack to about 7,000 by 1978. The 2008 figures released by the Turkish Foreign Ministry places the current number of Turkish citizens of Greek descent at the 3,000–4,000 mark. However according to the Human Rights Watch the Greek population in Turkey is estimated at 2,500 in 2006. The Greek population in Turkey is collapsing as the community is now far too small to sustain itself demographically, due to emigration, much higher death rates than birth rates and continuing discrimination.

The Greeks, also known as the Hellenes (Greek: Ἕλληνες, [ˈelines]), are a nation and ethnic group native to Greece, Cyprus and other regions. They also form a significant diaspora, with Greek communities established around the world.

Greek colonies and communities have been historically established in most corners of the Mediterranean, but Greeks have always been centered around the Aegean Sea, where the Greek language has been spoken since antiquity. Until the early 20th century, Greeks were uniformly distributed between the Greek peninsula, the western coast of Asia Minor, Pontus, Egypt, Cyprus and Constantinople; many of these regions coincided to a large extent with the borders of the Byzantine Empire of the late 11th century and the Eastern Mediterranean areas of the ancient Greek colonization.

In the aftermath of the Greco-Turkish War (1919–1922), a large-scale population exchange between Greece and Turkey transferred and confined Christians from Turkey, except Constantinople (effectively ethnic Greeks) into the borders of the modern Greek state and Cyprus. Other ethnic Greek populations can be found from southern Italy to the Caucasus and in diaspora communities in a number of other countries. Today, most Greeks are officially registered as members of the Greek Orthodox Church.

Turkey (Turkish: Türkiye), known officially as the Republic of Turkey ( Türkiye Cumhuriyeti (help·info)), is a Eurasian country located in Western Asia (mostly in the Anatolian peninsula) and in East Thrace in Southeastern Europe. Turkey is bordered by eight countries: Bulgaria to the northwest; Greece to the west; Georgia to the northeast; Armenia, Azerbaijan (the exclave of Nakhchivan) and Iran to the east; and Iraq and Syria to the southeast. The Mediterranean Sea and Cyprus are to the south; the Aegean Sea is to the west; and the Black Sea is to the north. The Sea of Marmara, the Bosphorus and the Dardanelles (which together form the Turkish Straits) demarcate the boundary between East Thrace and Anatolia; they also separate Europe and Asia.

Turkey is one of the six independent Turkic states. The vast majority of the population are Muslims. The country's official language is Turkish, whereas Kurdish and Zazaki languages are spoken by Kurds and Zazas, who constitute 18% of the population.

The Pontic Greeks of the Pontians (Greek: Πόντιοι, Turkish: Pontus Rumları) are an ethnic group traditionally living in the Pontus region, the shores of Turkey's Black Sea. They consist of Greek descendants and speak the Pontic Greek dialect, a distinct form of the standard Greek language which, due to the remoteness of Pontus, has had a process of linguistic evolution different from that of the rest of the Greek world.

Nowadays, due to extensive intermarriage (also with non-Pontic Greeks), the exact number of Greeks hailing from the Pontus, or people with Greek descent living there, is unknown. After 1988, Pontian Greeks in the Soviet Union started to migrate to Greece settling in and around Athens and Thessaloniki. They are known as "Russian Pontians" (Ρωσσοπόντιοι) by fellow Greeks. The largest communities of Pontian Greeks (or people of Pontian Greek descent) around the world are:

In Greek mythology the Black Sea region is the region where Jason and the Argonauts sailed to find the Golden Fleece.
