Christianity is the largest religion in Norway. Norway has historically been called a Christian country. A majority of the population are members of the Church of Norway with 71.5% of the population officially belonging to the Evangelical Lutheran Church of Norway in 2016. At numerous times in history, Norway sent more missionaries per capita than any other country. This changed considerably from the 1960s. In 2004, only 12% of the population attended church services each month. Citizens born in Norway to one or two Norwegian parents are automatically added to the list of Protestant Christians in Norway, and are required to "sign out" of the church. There are two categories kept in the church's books, "medlemmer" (members) and "tilhørige" (belonging to [the State church]). Members technically have to be baptised, whereas "tilhørige" are to be taken out of the books if not baptised by the age of 18. Norwegian citizens' tax funds are given to the Protestant Church until one registers as a member of another religious group, or as a member of the Humanist association.
The conversion of Norway to Christianity began in 1000 AD. The raids on Ireland, Britain and the Frankish kingdoms had brought the Vikings in touch with Christianity. Haakon the Good of Norway who had grown up in England tried to introduce Christianity in the tenth century, but had met resistance from pagan leaders and soon abandoned the idea.
Anglo-Saxon missionaries from England and Germany engaged in converting Norwegians to Christianity, but with limited success. However, they succeeded in converting Olaf I of Norway to Christianity. Olaf II of Norway (later Saint Olaf) had more success in his efforts to convert the population, and he is credited with Christianising Norway.
The Christians in Norway often established churches or other holy sites at places that had previously been sacred under the Norse religion. The spread of conversion can be measured by burial sites as Pagans were buried with grave goods while Christians weren't. Christianity had become well established in Norway by the middle of the 11th century and had become dominant by the middle of the 12th century. Stave churches were built of wood without the use of nails in the 13th century.

The above numbers reflect the percentage of the population that are members of a church, typically from being baptized as infants. Less than half of these define themselves as Christian. 
Early 21st century, Norway had one of the lowest church attendance rates in the world. Below is a table that compares Norway with other governmental divisions in regular church attendance for the early 21st century (2004-2006). In contrast to 250,000 regular churchgoers in the whole of Norway in 2004, 43,500 attend Lakewood Church in the United States each week, and 23,000 attend Hillsong Church in Australia each week.

The Evangelical Lutheran Free Church of Norway (Den Evangelisk Lutherske frikyrkja i Noreg in Norwegian) or the Free Church as it is commonly known, is a nationwide Lutheran church in Norway consisting of 81 congregations with 19,262 members in 2009. It was founded in 1877 in Moss. It should not be confused with the Church of Norway, though both churches are members of the Lutheran World Federation. The Free Church is economically independent.

The Catholic Church in Norway is part of the worldwide Catholic Church, under the spiritual leadership of the Pope and the Curia in Rome. Per 15 October 2012 the church had 115, 234 registered members. The number has increased from 59, 350 in 2008 due to high immigration. There may be approximately 170,000-200,000 people of Catholic background in the country, most of them immigrants.
The country is divided into three Church districts - the Diocese of Oslo and the prelatures of Trondheim and Tromsø and 32 parishes. The Bishop of Oslo participates in the Scandinavian Bishops Conference. The Catholic Church in Norway is as old as the kingdom itself, dating from approximately 900 A.D., with the first Christian monarchs, Haakon I from 934.
At first, the bulk of Catholic immigrants came from Germany, The Netherlands, and France. Immigration from Chile, the Philippines, and from a wide range of other countries began in the 1970s. This development has further increased in the last few years with economic immigrants from Poland and Lithuania. Ethnic Norwegian Catholics are now greatly outnumbered by the immigrants, although the former tend to be far more observant and conservative, being a self-selected group largely of ex-Lutheran converts.
Jehovah's Witnesses is the largest nontrinitarian religious organization in Norway, with a membership of 14,976 in 2009. A branch office is located in Ytre Enebakk. Jehovah's Witnesses receive public grants in the same manner as other registered religious communities in Norway.
