The Church of Norway is an evangelical Lutheran denomination of Protestant Christianity and by far the largest Christian church in Norway. The church became the state church of Norway around 1020, and was established as a separate church intimately integrated with the state as a result of the Lutheran reformation in Denmark–Norway which broke ties with the Holy See in 1536–1537; the King of Norway was the church's head from 1537 to 2012. Historically the church was one of the main instruments of royal power and official authority, and an important part of the state administration; local government was based on the church's parishes with significant official responsibility held by the parish priest.

The Preses of the Church of Norway is a titular bishop who leads the Bishops' Conference of the church as one who is primus inter pares. The name comes from the Latin word Praeses which means "placed before" or "at the head". In 2011, the office of Preses was changed by law to be a 12th permanent bishopric within the Church of Norway. Prior to 2011, it was an elected position from within the 11 diocesan bishops that made up the Bishops' Conference of the Church of Norway.
