Leinstrand is a former municipality in the old Sør-Trøndelag county, Norway. The municipality existed from 1838 until its dissolution in 1964. The municipality of Leinstrand encompassed the south-central part of what is now the city of Trondheim in Trøndelag county. The administrative centre was located in the village of Heimdal, just west of the border with Tiller municipality. The local Leinstrand Church was built in 1673. The municipality of Leinstrand was established on 1 January 1838 (see formannskapsdistrikt). According to the 1835 census, Leinstrand had a population of 1,165. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, the neighboring municipalities of Byneset (population: 2,049), Leinstrand (population: 4,193), Strinda (population: 44,600), Tiller (population: 3,595), and the city of Trondheim (population: 56,982) were merged to form the new urban municipality of Trondheim which would have a total population of 111,419. The municipality (originally the parish) is named Leinstrand (Leinastrǫnd). The first element comes from the old Leinan farm (Leinar). The name of the farm is the plural form of lein which means "slope". The last element is strǫnd which means "shore". While it existed, this municipality was responsible for primary education (through 10th grade), outpatient health services, senior citizen services, unemployment, social services, zoning, economic development, and municipal roads. During its existence, this municipality was governed by a municipal council of elected representatives, which in turn elected a mayor.
