According to various polls, the majority ofKazakhstan's citizens, primarily ethnicKazakhs, identify asSunni Muslims.[2][3]
According to the 2021 census, 69.3% of the population isMuslim, 17.2% areChristian, 0.2% follow other religions (mostlyBuddhist andJewish), 11.01% chose not to answer, and 2.25% identify asatheist.[4]
There are a total of 3,000 mosques,[5] all of them affiliated with the "Spiritual Association of Muslims of Kazakhstan", headed by a suprememufti.[6] TheEid al-Adha is recognized as a national holiday.[5]
In 2020, 20% of the population was Orthodox Christian, traditionally including ethnic Russians, Ukrainians and Belarusians.[7] In 2011, other Christian groups in the country includedCatholics andProtestants (Baptists,Presbyterians,Lutherans,Pentecostals,Methodists,Mennonites andSeventh-day Adventists), including restorationist Christian faiths such asJehovah's Witnesses andThe Church of Jesus Christ of Latter Day Saints.[8] In 2011 there were a total of 175 registered Orthodox churches, 53 Catholic churches, and 343 Protestant churches and prayer houses; other religious registered groups includedJudaism, theBaháʼí Faith,Hinduism,Buddhism, theChurch of Scientology,Christian Science, and theUnification Church.[8] TheAhmadiyya community is not registered despite several attempts since 2011.[9]
Christmas, rendered in the Russian Orthodox manner according to theJulian calendar, is recognized as a national holiday in Kazakhstan.[5]
The government considers several religions as 'traditional', includingHanafi Sunni Islam, theRussian Orthodox Church, Greek and Roman Catholicism,Lutheranism, and Judaism; some parts of the country can be wary of members of 'nontraditional' minority religious groups.[9]
In 2022, President Tokayev stated that the country was a "secular and tolerant country" but noted that the authorities will not "turn a blind eye to various radical movements and religious separatism.”[9]

The country has historically hosted a wide variety of ethnic groups with varying religions. The foundation of an independent republic, following the disintegration of the USSR, has launched a great deal of changes in every aspect of people's lives. Religiosity of the population, as an essential part of any cultural identity, has undergone dynamic transformations as well.
Baptist Churches are often raided. This is due to the church members gathering without registering themselves, a requirement of the country. Anyone who does not register risk being raided by the police. However not only those that violate the law are treated harshly.[10]
On May 2, 2017, a court in the capital of Astana, Kazakhstan, sentenced a 61-year-old man to a five-year prison sentence for performing Bible education work. Teymur Akhmedov, is a member of Jehovah's Witnesses. The court called his preaching and teaching efforts “inciting religious discord” and “advocating [religious] superiority.” In addition, the judge also imposed a three-year ban on Mr. Akhmedov’s participation in Bible education activities. Mr Akhmedov's medical issues were not considered, as he requires treatment for a bleeding tumor and has been denied the medical attention that he requires.[11]
After decades of suppressed culture, the people were feeling a great need to exhibit their ethnic identity - in part through religion. Quantitative research shows that for the first years after the establishment of the new laws, waiving any restrictions on religious beliefs and proclaiming full freedom of confessions, the country experienced a huge spike in religious activity of its citizens. Hundreds of mosques, synagogues, churches, and other religious structures were built in a matter of years. All represented religions benefited from increased number of members and facilities. Many confessions that were absent before independence made their way into the country, appealing to hundreds of people. The government supported this activity, and has done its best to provide equality among all religious organizations and their followers. In the late 1990s, however, a slight decline in religiosity occurred.[citation needed] The draft religion law being considered in June 2008 has raised international concern over whether there is an intention to meet general standards of freedom of religion and human rights.[12]

Islam is the most commonly practiced religion in Kazakhstan; it was introduced to the region during the 9th century.[13] Traditionally ethnic Kazakhs are Muslims who mainly follow theHanafi school.[14]
Kazakhs including other ethnic groups of Muslim background make up over 90 per cent of all Muslims.[15] The southern region of the country has the highest concentration of self-identified practicing Muslims.

Christianity in Kazakhstan is the second most practiced religion afterIslam. Most Christian citizens areRussians, and to a lesser extentUkrainians andBelarusians, who belong to theRussian Orthodox Church.
The 2021 census noted thatKazakhstan is 17.19%Christian.[16] Other figures suggest that 24% of the population is Orthodox, 1% is either Catholic or Protestant and 1% belongs to other Christian denominations.[7]
In 2009, Christian groups includedLutheranism,Presbyterians,Methodists,Seventh-day Adventists,Pentecostals,Baptist (Union of Evangelical Christian Baptists of Kazakhstan),Mennonites andMormons.[14][17]
Jehovah's Witnesses are also present in the country although the group faces many restrictions by the government in the past.[18][19][20][21]
"Kazakhstan is the strange core of traditionalist Catholicism," Catholic writerRoss Douthat stated in 2018.[22]
TheBaháʼí Faith in Kazakhstan began during thepolicy of oppression of religion in the formerSoviet Union. Before that time,Kazakhstan, as part of theRussian Empire, would have had indirect contact with the Baháʼí Faith as far back as 1847.[23] Following the entrance ofBaháʼí pioneers the community grew to be the largest religious community after Islam and Christianity, though only a few percent of the nation.[24] By 1994 the National Spiritual Assembly of Kazakhstan was elected[25] and the community has begun to multiply its efforts across various interests. TheAssociation of Religion Data Archives (relying onWorld Christian Encyclopedia) estimated some 7,000 Baháʼís in 2010.[26]

Kazakh Jews have a long history. There are approximately 2,500-3,300Jews inKazakhstan, less than 1% of the population. Most Kazakh Jews areAshkenazi and speakRussian.[27][28]
Buddhism has existed in Kazakhstan since the 17th century, which is evidenced by the ancient pagodas and temples discovered by scientists during excavations. At present, there are only two officially registered Buddhist organisations in Kazakhstan, one belongs toWon Buddhism that originated from Korea and the other organization belongs to Tibetan Buddhism.[29]
According to the 2009 Census, there were 14,663 Buddhists in Kazakhstan. Also, according to from general Population census results of the Kazakhstan 2021, there are around 15,458 Buddhists in the country
Hindus inKazakhstan are mainly composed of theISKCON sect and Diaspora Hindus from India. There were about 801 Hindus in Kazakhstan in 2010 according toARDA.[30]
Tengrism is aCentral Asianreligion characterized byshamanism,animism,totemism,poly- andmonotheism andancestor worship. It was the prevailing religion of theTurks,Mongols,Hungarians,Xiongnu andHuns, and the religion of the five ancient Turkic states:Göktürk Khaganate,Western Turkic Khaganate,Great Bulgaria,Bulgarian Empire andEastern Tourkia (Khazaria). InIrk Bitig, Tengri is mentioned asTürük Tängrisi (God of Turks).
Tengrists view their existence as sustained by the eternal blue sky (Tengri), the fertile mother-earth spirit (Umay) and a ruler regarded as the holy spirit of the sky. Heaven, earth, spirits of nature and ancestors provide for every need and protect all humans. By living an upright, respectful life, a human will keep his world in balance and perfect his personalWind Horse, or spirit. The Huns of the northern Caucasus reportedly believed in two gods: Tangri Han (or Tengri Khan), considered identical to the PersianAspandiat and for whom horses were sacrificed, and Kuar (whose victims are struck by lightning). Tengrism is practiced inKazakhstan,Sakha,Buryatia,Tuva andMongolia in parallel withTibetan Buddhism andBurkhanism.
Kazakhstan has a very diverse and stable religious background. However, some reported occurrences of persecution against Hare Krishnas and Jehovah's Witnesses for proselytizing have raised concern in the international community.[31][32][33]
Article 22 of the Constitution of the Republic of Kazakhstan states that "everyone has the right to a freedom of conscience.” On May 18, 2011, the President of Kazakhstan adopted a decree establishing the Agency for Religious Affairs. The mission of the Agency is to coordinate interaction between the government, religious groups and civil society in order to ensure religious freedom in Kazakhstan.[34]
In 2003 Kazakhstan established Congress of Leaders of World and Traditional Religions, that aims to facilitate religious dialogue ensuring inter-religious tolerance, and freedom in Kazakhstan.[35]
In 2023, the country was scored 1 out of 4 for religious freedom.[36] It was noted that legal amendments in 2022 placed extra restrictions on citizens.
