According to various polls, the majority of Kazakhstan's citizens, primarily ethnic Kazakhs, identify as Sunni Muslims.^[2][3]

According to the estimate by the Pew Research Center, 71% of the population practices the religion of Islam. It also estimated that 17% practices Christianity, 10% are unaffiliated, and 0.9% of the population practices other religions, mainly Buddhism and Folk Religion.^[4]

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 husband and father of three sons to a five-year prison sentence for performing peaceful 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]

"Kazakhstan is the strange core of traditionalist Catholicism," Catholic writer Ross Douthat stated in 2018.^[22]

The Baháʼí Faith in Kazakhstan began during the policy of oppression of religion in the former Soviet Union. Before that time, Kazakhstan, as part of the Russian Empire, would have had indirect contact with the Baháʼí Faith as far back as 1847.^[23] Following the entrance of Baháʼí 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. The Association of Religion Data Archives (relying on World Christian Encyclopedia) estimated some 7,000 Baháʼís in 2010.^[26]

• Slavic Neopaganism

Tengrism is a Central Asian religion characterized by shamanism, animism, totemism, poly- and monotheism and ancestor worship. It was the prevailing religion of the Turks, Mongols, Hungarians, Xiongnu and Huns, and the religion of the five ancient Turkic states: Göktürk Khaganate, Western Turkic Khaganate, Great Bulgaria, Bulgarian Empire and Eastern Tourkia (Khazaria). In Irk Bitig, Tengri is mentioned as Türük 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 personal Wind Horse, or spirit. The Huns of the northern Caucasus reportedly believed in two gods: Tangri Han (or Tengri Khan), considered identical to the Persian Aspandiat and for whom horses were sacrificed, and Kuar (whose victims are struck by lightning). Tengrism is practiced in Kazakhstan, Sakha, Buryatia, Tuva and Mongolia in parallel with Tibetan Buddhism and Burkhanism.

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]
