What Religion Are Turkish People? A Clear 2026 Answer

The short answer is Islam. Most Turkish people are Muslim, and across recent surveys the figure usually lands somewhere between 94% and 98% of the population identifying as Muslim, with a 2025 Pew estimate putting it at around 95%. But “Turkish people are Muslim” is true the same way “British people are Christian” is true. It tells you the official majority and almost nothing about how people actually live, pray, drink, or vote. So let me give you the fuller version, because that nuance is exactly what trips up first-time visitors.

What religion are Turkish people, really?

Islam is the dominant religion in Turkey, full stop. Where the numbers get interesting is in the gap between cultural identity and active belief. A huge share of people who tick “Muslim” on a survey are Muslim the way many Europeans are culturally Christian: it shapes holidays, food, family rituals, and funerals, but day-to-day religious observance ranges from devout to barely-there.

The denominations matter too. The overwhelming majority of Turkish Muslims are Sunni, roughly 85 to 90% of the Muslim population, and most of those follow the Hanafi school of jurisprudence. A 2023 study found about 62% identifying with Hanafi and around 9% with the Shafi’i school, which is dominant in the Kurdish-majority southeast. Then there are the Alevis, a distinct branch with its own rituals, music, and worship spaces called cemevis rather than mosques. Alevi population estimates are notoriously slippery (Turkish censuses do not ask about sect), with figures ranging anywhere from a few million to well over twenty million. Take any single number with caution.

If you want a sense of how this Islamic culture shapes the city around you, our piece on Turkish culture and everyday customs walks through the rhythms you will actually notice.

Is Turkey a Muslim country or a secular one?

Both, and that tension is the whole point. Turkey is constitutionally a secular state. The 1982 constitution recognizes no official religion and is built on the principle of laiklik, the Turkish take on French-style laicism. In practice this is not a hands-off neutrality. The state actively manages religion through a powerful body called the Diyanet (the Presidency of Religious Affairs), which runs roughly 77,500 mosques, pays imams’ salaries, and signs off on the Friday sermons preached nationwide. So religion is everywhere in public life, but it is channeled through a government department rather than an independent clergy.

What this means on the ground: you will hear the call to prayer five times a day, you will see mosques on practically every corner, and you will also see crowded bars, women in everything from headscarves to crop tops on the same street, and people who fast all of Ramadan sitting next to people who do not fast at all. Istanbul in particular holds these contradictions comfortably. If you are wondering how that fits with the broader question of where the country sits culturally, we get into it in is Turkey considered part of Europe.

Are young Turkish people becoming less religious?

Yes, and this is the genuinely new part of the story. Long-running polling shows a real shift. KONDA Research, which has tracked Turkish lifestyles for years, found the share of people describing themselves as “devout” dropped from about 55% in 2008 to roughly 46% by 2025, while those identifying as atheist or nonbeliever rose from around 2% to about 8% over the same period.

The trend is sharpest among the young. By recent counts, somewhere around one in ten Turks aged 18 to 24 say they do not believe in God, and university-campus studies have found notable shares describing themselves as deist, atheist, or agnostic. Researchers tend to credit growing individualism, easy access to global ideas online, and a pushback against religion being so closely tied to politics. None of this makes Turkey a secular-atheist country. It is still overwhelmingly Muslim by identity. But the old assumption that every Turk is a practicing believer is increasingly out of date, especially in big cities like Istanbul, Izmir, and Ankara.

What about non-Muslim minorities?

They exist, they are historically important, and they are small. Christians (Greek Orthodox, Armenian Apostolic, Syriac, and others) along with the Sephardic Jewish community together make up only about 0.2% of the population today, a fraction of what these communities once were. You can still trace this older, layered Istanbul if you know where to look: the churches and synagogues tucked into neighborhoods like Fener and Balat are some of the most atmospheric spots in the city, and several historic churches are still active places of worship. For a wider look at the human side of all this, what Istanbul’s people are really like is a good companion read.

How does this affect you as a visitor?

This is the part travelers actually care about, so let me be practical.

You absolutely can drink alcohol. It is legal, widely available in restaurants, bars, and shops, and rakı is basically the national drink. It is taxed heavily so it is not cheap, but nobody will look twice. We cover the specifics in can you drink alcohol in Istanbul.

Dress is relaxed in cities. There is no nationwide dress code, and you will see the full range of styles on any Istanbul street. The one firm rule is mosque etiquette: cover shoulders and knees, women cover their hair with a scarf, and everyone removes shoes before entering. Most major mosques keep scarves and wraps by the door for visitors. If mosque-visiting is high on your list, the most beautiful mosques in Istanbul is the route I would plan around.

Timing is worth knowing. During Ramadan, daytime life carries on largely as normal in tourist areas, but the evening iftar (the meal that breaks the fast) is a wonderful, communal thing to witness and join. Our Ramadan in Istanbul guide explains what changes and what does not. And yes, Turks celebrate plenty beyond the Islamic calendar, including a surprisingly festive secular New Year, which we cover in how Turkish people celebrate Christmas and New Year.

The honest takeaway

So, what religion are Turkish people? Predominantly Muslim, predominantly Sunni Hanafi, inside a constitutionally secular state, with a growing and openly secular younger generation and small but historically vital Christian and Jewish minorities. If a single label feels too neat, that is because it is. The country is genuinely both deeply Muslim and genuinely secular at the same time, and learning to hold both ideas at once is the fastest way to understand modern Turkey. If you are curious where this population came from in the first place, that is a whole story of its own, told in where Turkish people are originally from.
