Nord-Trøndelag was a county constituting the northern part of the present-day Trøndelag county in Norway. It bordered the old Sør-Trøndelag county as well as the county of Nordland. To the west is the Norwegian Sea, and to the east is Jämtland in Sweden. The county was established in 1804 when the old Trondhjems amt was divided into two: Nordre Trondhjems amt and Søndre Trondhjems amt. In 2016, the two county councils voted to merge (back) into a single county on 1 January 2018.
