The List of churches in Sør-Trøndelag is a list of the Church of Norway churches in Sør-Trøndelag county, Norway. The churches are all part of the Diocese of Nidaros, and the list is divided into eight sections, one for each Deanery (prosti) in the diocese, although some deaneries overlap counties with parts in both Sør-Trøndelag and Nord-Trøndelag. Administratively within each deanery, the churches are divided by municipalities which have their own church council (fellesråd) and then into parishes (sokn) which have their own councils (soknerådet). Each parish may have one or more congregations in it.
