Finland is a predominantlyChristian nation where 62.2 % of the Finnish population of 5.6 million are members of theEvangelical Lutheran Church of Finland (Protestant), 34.9 % areunaffiliated, 1.0% areOrthodox Christians, and 1.8 % follow other religions.[1] These statistics do not include, for example, asylum seekers who have not been granted a permanent residence permit.[2]
There are twonational churches, theEvangelical Lutheran Church of Finland (Protestant) and theFinnish Orthodox Church.[3][4]Those who officially belong to one of the two national churches have part of their taxes turned over to their respective church (approximately 1-2% of income).[5]
There are also approximately 44,000 followers ofPentecostal Christianity,[6] and more than 15,000 Catholics in Finland, along with Anglicans, and some various Independent Christian communities. Prior to its Christianisation, beginning in the 11th century,Finnish paganism was the country's primary religion.

Most Finns are members of the Evangelical Lutheran Church of Finland (62.2%).[8] With about 3.5 million members out of a total population of 5.6 million,[7] the Evangelical Lutheran Church of Finland remains one of the largest Lutheran churches in the world, though its membership is declining. In 2023,Eroakirkosta.fi, a website which offers an electronic service for resigning from Finland's national churches, reported that more than 850,000 people had resigned their membership in the churches since the website was opened in 2003.[10] The number of church members leaving the Church saw a particular large increase during the fall of 2010. This was caused by statements regarding homosexuality and same-sex marriages perceived to be intolerant towardsLGBT people made by a conservative bishop and a politician representingChristian Democrats in a TV debate on the subject.[11] The second largest group – and a rather quickly growing one – of 34.9% by the end of 2024 of the population is non-religious. A small minority belong to theFinnish Orthodox Church (1.0%) and to theCatholic Church (15,982 people or 0.3% of the population).[8]
OtherProtestant denominations are significantly smaller, as are theSikhs,Jewish,Muslim,Buddhist,Hindu and other non-Christian communities (totaling with the Catholics to about 1.8% of the population).
The main Lutheran and Orthodox churches are constitutionalnational churches of Finland with special roles in ceremonies and often in school morning prayers. Delegates to Lutheran Church assemblies are selected in church elections every four years.
The majority of Lutherans attend church only for special occasions like Christmas, Easter, weddings and funerals. The Lutheran Church estimates that approximately 2 percent of its members attend church services weekly. In 2004, the average number of church visits per year by church members is approximately two.[12]
According to theEurobarometer Poll (2010),[13]
According to Zuckerman (2005), various studies have claimed that 28% of Finns "do not believe in God" and 33 to 60% do not believe in "a personal God".[14]
In 2024, the Evangelical-Lutheran Church of Finland had about 3.5 million members, which is 62.2% of the population, registered with a parish. The Evangelical Lutheran Church of Finland is an episcopal church, that is governed by bishops, with a very strong tradition of parish autonomy. It comprises nine dioceses with ten bishops and 384 independent parishes.[15] The average parish has 7,000 members, with the smallest parishes comprising only a few hundred members and the largest tens of thousands.[16] In recent years many parishes have united in order to safeguard their viability. In addition, municipal mergers have prompted parochial mergers as there may be only one parish, or cluster of parishes, in a given municipality.[citation needed]

TheFinnish Orthodox Church (Finnish:Suomen ortodoksinen kirkko;Swedish:Ortodoxa kyrkan i Finland), orOrthodox Church of Finland, is an autonomousEastern Orthodox archdiocese of theEcumenical Patriarchate of Constantinople. The Church has a legal position as anational church in the country, along with the Evangelical Lutheran Church of Finland. With its roots in the medievalNovgorodian missionary work inKarelia, the Finnish Orthodox Church was a part of theRussian Orthodox Church until 1923. Today the church has three dioceses and approximately 58,000 members that account for 1 percent of the native population ofFinland. The parish ofHelsinki has the most adherents.

The Catholic Church in Finland is part of the worldwideCatholic Church, under the spiritual leadership of thePope inRome. As of 2020 there were 16,000 Catholics out of the country's population of 5.5 million.[17] There are estimated to be more than 6,000 Catholic families in the country, about half native Finns and the rest from international communities.
As of 2018 there are only five Finnish-born priests, and only three of them work in Finland. The currentBishop of Helsinki is Mons.Raimo Goyarrola (appointed 29 September 2023), who succeeded BishopTeemu Sippo after he abdicated in May 2019 due to old age. Bishop Sippo is the first Finn to serve as a Catholic bishop in over 500 years. Currently there are more than 30 priests working in Finland from different countries. Due to the small number of Catholics in Finland, the whole country forms a single diocese, theCatholic Diocese of Helsinki. The Catholic Church in Finland is active inecumenical matters and is a member of theFinnish Ecumenical Council, even though the worldwide Catholic Church is not a member of theWorld Council of Churches.
Baptists in Finland have existed since the middle of the 19th century[18] and are part of theBaptist branch ofProtestant Christianity. They were among the earlyfree churches in Finland. There are three church associations, theFinnish Baptist Church (Finnish:Suomen Baptistikirkko),Swedish Baptist Union of Finland (Swedish:Finlands svenska baptistsamfund), and two congregations belonging to theSeventh Day Baptists. Additionally, there are several independent Baptist churches. The Baptist movement came to Finland from Sweden in the mid-1800s.[19] The Swedish Baptist Union of Finland includes 13 congregations with approximately 1000 members.[20] The Finnish Baptist Church consists of 14 congregations with about 1500 members.[21] The Seventh Day Baptist Fellowship includes two congregations with 35 members. The membership and congregation numbers of the independent Baptist churches are unknown.
Finnish Neopaganism, or theFinnish native faith (Finnish:Suomenusko: 'Finnish Faith') is the contemporaryNeopagan revival ofFinnish paganism, the pre-Christianpolytheisticethnic religion of theFinns. A precursor movement was theUkonusko ('Ukko's Faith', revolving around the godUkko) of the early 20th century. The main problem in the revival of Finnish paganism is the nature of pre-Christian Finnish culture, which relied on oral tradition and of which very little is left. The primary sources concerning Finnish native culture are written by latter-era Christians. There are two main organisations of the religion, the Association of Finnish Native Religion (Suomalaisen kansanuskon yhdistys ry) based in Helsinki and officially registered since 2002, and the Pole Star Association (Taivaannaula ry) headquartered inTurku with branches in many cities, founded and officially registered in 2007. The Association of Finnish Native Religion also caters toKarelians and is a member of theUralic Communion.
Buddhism in Finland represents a very small percentage of that nation's religious practices. In 2013 there were 5,266 followers of Buddhism in Finland, 0.1% of the population.[22] There are currently 12 Finnish cities that have Buddhist temples: in Helsinki,Hyvinkää,Hämeenlinna,Jyväskylä,Kouvola,Kuopio,Lahti,Lappeenranta,Pori,Salo,Tampere andTurku.[citation needed]
While no statistics on the numbers of Baha'is have been released, the Evangelical Lutheran Church of Finland estimated the 2004 population of Bahá'ís to be approximately 500.Operation World, another Christian organization, estimated 0.01%, also about 500 Bahá'ís, in 2003.
In 2020 there was an estimate of 1668 Baha'í followers, according to theAssociation of Religion Data Archives (relying onWorld Christian Encyclopedia).[23]
Hinduism is a very minorreligious faith in Finland. There are estimated to be around 5,000 Hindus in Finland, mostly from India, Nepal and Sri Lanka. Finland acquired a significantHindu population for the first time around the turn of the 21st century due to the recruitment ofinformation technology workers from India by companies such asNokia.[24] In 2009, Hindu leaders in Finland protested the inclusion of a photograph that "denigrates Hinduism" in an exhibit at theKiasma Museum of Contemporary Art. The museum later removed the picture from its website.[25]
The firstMuslims wereTatars who immigrated mainly between 1870 and 1920. After that there were decades with generally a small number ofimmigration in Finland. Since the late 20th century the number of Muslims in Finland has increased rapidly due to immigration.
According to the Finland official census (2022), there are 22,261 people in Finland belonging to registered Muslim communities.[26] However, the vast majority of Muslims in Finland do not belong to any registered communities. It is estimated that there are between 120,000 and 130,000 Muslims in Finland (2.3%).[27]
Finnish Jews areJews who arecitizens ofFinland. The country is home to approximately 1,000 Jews in 2022,[7] who mostly live in Helsinki. Jews came to Finland as traders and merchants from other parts of Europe. During the1948 Arab–Israeli War, about 28 Finnish Jews, mostly Finnish Army veterans, fought for theState of Israel. After Israel's establishment, Finland had a high rate of immigration to Israel (known asaliyah), which depleted Finland's Jewish community. The community was somewhat revitalized when some Soviet Jews immigrated to Finland following the collapse of the Soviet Union. The number of Jews in Finland in 2010 was approximately 1,500, of whom 1,200 lived in Helsinki, about 200 in Turku, and about 50 inTampere. Jews are well integrated into Finnish society and are represented in nearly all sectors. Most Finnish Jews are corporate employees or self-employed professionals. Most Finnish Jews speakFinnish orSwedish as theirmother tongue.Yiddish,German,Russian, andHebrew are also spoken in the community. Jews, like Finland's other traditional minorities as well as immigrant groups, are represented on the advisory board for Ethnic Relations (ETNO).There are two synagogues:one in Helsinki andone in Turku. Helsinki also has aJewish day school, which serves about 110 students (many of them the children ofIsraelis working in Finland); and aChabad Lubavitch rabbi is based there. Tampere previously had an organized Jewish community, but it stopped functioning in 1981. The other two cities continue to run their community organizations.

Traditionally, the church has played a very important role in maintaining a population register in Finland. The vicars have maintained a church record of persons born, married and deceased in their parishes since at least the 1660s, constituting one of the oldest population records in Europe. This system was in place for over 300 years. It was only replaced by a computerised central population database in 1971, while the two national churches continued to maintain population registers in co-operation with the government's local register offices until 1999, when the churches' task was limited to only maintaining a membership register.[29]
Between 1919 and 1970, a separate Civil Register was maintained of those who had no affiliation with either of the national churches.[29] Currently, the centralised Population Information System records the person's affiliation with a legally recognised religious community, if any.[30] In 2003, the new Freedom of Religion Act made it possible to resign from religious communities in writing. That is, by letter, or any written form acceptable to authorities. This is also extended toemail by the 2003 electronic communications in the public sector act.[31] Resignation by email became possible in 2005 in most magistrates.Eroakirkosta.fi, an Internet campaign promoting resignation from religious communities, challenged the rest of the magistrates through a letter to theparliamentary ombudsman. In November 2006, the ombudsman recommended that all magistrates should accept resignations from religious communities via email.[32] Despite the recommendation by the ombudsman, the magistrates of Helsinki and Hämeenlinna do not accept church membership resignations sent via the Eroakirkosta.fi service.[33]
