North Dorset was a local government district in Dorset, England, between 1974 and 2019. Its area was largely rural, but included the towns of Blandford Forum, Gillingham, Shaftesbury, Stalbridge and Sturminster Newton. Much of North Dorset was in the River Stour valley, known as the Blackmore Vale. The economy of North Dorset was largely based on dairy agriculture.

The district was formed on 1 April 1974, under the Local Government Act 1972, from the municipal boroughs of Blandford Forum, Shaftesbury, Blandford Rural District, Shaftesbury Rural District and Sturminster Rural District. The district and its council were abolished on 1 April 2019 and, together with the other four Dorset districts outside the greater Bournemouth area, incorporated into a Dorset unitary authority.

At the 2001 UK census North Dorset had a population of 61,905, a rise of 8,300 from 1991, with 25,248 households.

North Dorset is home to North Dorset Rugby Football Club.

North Dorset District Council had its main offices at a large converted house called Nordon on Salisbury Road, Blandford Forum, which had previously been the offices of the Blandford Rural District Council, one of the council's predecessors. Councillors were elected every four years; the final election before abolition was held in 2015.
