=== Kristen ===
Agama [[Kristen]] telah hadir jauh lebih dulu daripada agama Islam yang menjadi agama sebagian besar penduduk Turki saat ini. Agama Kristen memiliki sejarah panjang di wilayah [[Asia Kecil]] dan dataran tinggi Armenia yang kini masuk kedalam wilayah kekuasaan negara Turki. Turki menjadi tempat lahirnya beberapa [[Santo|orang suci]] dan salah satu dari [[Kedua belas Rasul|dua belas murid Yesus]]. Tokoh-tokoh Kristen tersebut antara lain adalah [[Paulus dari Tarsus]], [[Santo Timotius]], [[Nikolas dari Myra|Santo Nikolas dari Myra]], [[Polikarpus|Santo Polikarpus]]., dan masih banyak lainnya.<ref>{{Cite web|url=http://www.catholic.org/saints/|title=Saints & Angels - Catholic Online|last=Online|first=Catholic|website=Catholic Online|language=en|access-date=2017-12-10}}</ref><ref>{{Cite book|url=https://books.google.com/books?id=jhr28NT_HnYC&pg=PR62&lpg=PR62&dq=paulus+tarsus&source=bl&ots=Td_1o3pqbs&sig=1ZirQNwbsjNdE0Z9VQfJWKCvhzg&hl=id&sa=X&ved=0ahUKEwijwZDJ8__XAhUQyWMKHUPfC7MQ6AEIYjAJ#v=onepage&q=paulus%20tarsus&f=false|title=Paulus of Tarsus: A Man Driven by the Word|last=Phd|first=Verling Chako Priest|date=2012-03|publisher=Trafford Publishing|isbn=9781466920910|language=en}}</ref>

Jumlah orang Kristen di Turki mengalami penurunan yang sangat signifikan pada rentang tahun 1914 hingga 1927. Tercatat jumlah penganut agama Kristen di tahun 1914 adalah 19% dari total penduduk Turki dan menyusut tajam menjadi hanya 2,5% saja di tahun 1927.<ref name=":1" /> Hal ini terjadi karena perubahan struktur demografi Turki akibat dampak [[Perang Dunia I|Perang Dunia Pertama]]. Gelombang [[emigrasi]] orang-orang Kristen yang tinggal Turki; seperti [[orang Asiria]], [[orang Yunani]], [[orang Armenia]] dan lain-lain; ke luar meninggalkan Turki ke negara lain (sebagian besar ke benua Eropa dan benua Amerika). Saat ini tercatat ada sekitar 160.000 atau 0,2% penganut agama Kristen dengan berbagai denominasi menetap di Turki. Mayoritas denominasi Kristen di Turki adalah gereja-gereja [[Ritus Timur|ritus timur]]. Diantara denominasi Kristen tersebut terdapat sekitar 80.000 jemaat [[Gereja Ortodoks Oriental]], 35.000 orang pengikut [[Gereja Katolik Roma]], sekitar 18.000 orang menjadi jemaat Gereja [[Antiokhia Yunani]], 5.000 orang jemaat [[Gereja Ortodoks Yunani]], dan 8.000 orang lainnya adalah penganut ajaran [[protestanisme]] (berbagai denominasi protestan).<ref name=":0" /><ref name=":1" /><ref name=":2" />
[[File:Agia Triada Greek Orthodox Church, İstanbul.jpg|thumb|[[Hagia Triada Greek Orthodox Church, Istanbul|Aya Triada Greek Orthodox church]] in [[Beyoğlu]], Istanbul]][[Orthodox Christianity]] forms a tiny minority in Turkey, comprising far less than one tenth of one percent of the entire population. The provinces of [[Istanbul Province|Istanbul]] and [[Hatay Province|Hatay]], which includes Antakya, are the main centres of Turkish Christianity, with comparatively dense Christian populations, though they are very small minorities. The main variant of Christianity present in Turkey is the [[Eastern Orthodox]] branch, focused mainly in the [[Greek Orthodox|Greek Orthodox Church]].
Terdapat pula sebagian kecil orang [[Orang Turki|Turki]] yang menganut agama Kristen Ortodoks, kebanyakan dari mereka bergabung menjadi jemaat [[Gereja Ortodoks Yunani]] ataupun [[Gereja Ortodoks Siria]]. Orang-orang Turki yang menganut agama Kristen ini banyak terdapat di kota [[Istanbul]] dan Kota [[İzmir]], Orang Turki Kristen seringkali salah dianggap sebagai orang Yunani. Sebagian dari mereka memang memiliki latar belakang keturunan Yunani, namun secara etnis mereka adalah termasuk kedalam golongan [[orang Turki]]. Populasi orang Kristen Turki ini terbentuk sejak zaman [[Kesultanan Utsmaniyah|Kekhalifaan Utsmaniyah]], mereka berasal dari orang-orang Turki asli yang menolak untuk masuk Islam. <ref>{{Cite news|url=https://www.christiancentury.org/article/2011-03/turkish-protestants-still-face-long-path-religious-freedom|title=Turkish Protestants still face "long path" to religious freedom|newspaper=The Christian Century|language=en|access-date=2017-12-10}}</ref> Tercatat ada 236 buah gereja yang aktif melakukan pelayanan di seluruh wilayah negara Turki.<ref>{{Cite web|url=https://web.archive.org/web/20090415000147/http://www.goturkey.com/Life--Culture-Religion--51538-c-en.html|title=goTurkey.com|date=2009-04-15|access-date=2017-12-10}}</ref>
