Armenians in Turkey, one of the indigenous peoples of Turkey, have an estimated population of 50,000 to 70,000, down from a population of over 2 million Armenians between the years 1914 and 1921. Today, the overwhelming majority of Turkish Armenians are concentrated in Istanbul. They support their own newspapers, churches and schools, and the majority belong to the Armenian Apostolic faith and a minority of Armenians in Turkey belong to the Armenian Catholic Church or to the Armenian Evangelical Church. They are not considered part of the Armenian Diaspora, since they have been living in their historical homeland for more than four thousand years.

Armenian is an Indo-European language and the sole member of an independent branch of that language family. It is the native language of the Armenian people and the official language of Armenia. Historically spoken in the Armenian highlands, today Armenian is widely spoken throughout the Armenian diaspora. Armenian is written in its own writing system, the Armenian alphabet, introduced in 405 AD by the canonized saint Mesrop Mashtots. The estimated number of Armenian speakers worldwide is between five and seven million.
