Nord-Trøndelag County Municipality (Norwegian: Nord-Trøndelag fylkeskommune) was the regional governing administration of the old Nord-Trøndelag county in Norway. The county municipality was established in its current form on 1 January 1976 when the law was changed to allow elected county councils in Norway. The county municipality was dissolved on 1 January 2018, when Nord-Trøndelag was merged with the neighboring Sør-Trøndelag county, creating the new Trøndelag county which is led by the Trøndelag County Municipality.

The main responsibilities of the county municipality included the running of 12 upper secondary schools, with 7,000 pupils. It administered the 1,771 kilometres (1,100 mi) of county roadways, public transport, dental care, culture and cultural heritage. The administration is located in Steinkjer.

The Nord-Trøndelag county council (Norwegian: Fylkestinget) was made up of 35 representatives that were elected every four years. The council essentially acted as a Parliament or legislative body for the county and it met several times each year. The council was led by the County Mayor (fylkesordfører) who held the executive powers of the county along with a smaller group known as the county cabinet. The last county mayor of Nord-Trøndelag, was Gunnar Viken (Conservative Party) while his deputy is Johannes Sandstad (Christian Democratic Party). The county cabinet was led by Anne Marit Mevassvik and has four members, from the Labour Party, the Conservative Party and the Christian Democratic Party.
