This list of churches in Tunsberg is a list of the Church of Norway churches in the Diocese of Tunsberg in Norway. It includes all of the parishes in Buskerud and Vestfold counties. The diocese is based at the Tønsberg Cathedral in the city of Tønsberg in Tønsberg Municipality, Vestfold county. The diocese was formally established in 1948 when it was separated from the large Diocese of Oslo, although the occupation government during World War II also temporarily established the diocese of Tunsberg from 1942 to 1945, but that was not recognized by the King or the government-in-exile during the war.
 The list is divided into several sections, one for each deanery (prosti; headed by a provost) in the diocese. Administratively within each deanery, the churches within each municipality elects their own church council (fellesråd). Each municipality may have one or more parishes (sokn) within the municipality. Each parish elects their own councils (soknerådet). Each parish has one or more local church. The number and size of the deaneries and parishes has changed over time.
