Vinje is a former municipality in the old Sør-Trøndelag county, Norway. The 222-square-kilometre (86 sq mi) municipality existed from 1924 until its dissolution in 1964. The municipality encompassed the areas around the inner Vinjefjorden and the Søo river valley in what is now the southern part of the present-day municipality of Heim. The administrative centre was the village of Vinjeøra. The lake Vasslivatnet lies in the eastern part of Vinje.^[2]

Originally (since 1838), Vinje was a part of the municipality of Hemne (see formannskapsdistrikt law). Historically, the parish annex of Vinje actually belonged to Romsdalen county while the main parish of Hemne belonged to Søndre Trondhjem county. But according to the 1837 formannskapsdistrikt law, a parish could no longer be divided between two counties, so the annex of Vinje had to be transferred to the county of Søndre Trondhjem.^[3]

On 1 July 1924, the large municipality of Hemne was divided into Vinje municipality (population: 716) in the south, Snillfjord municipality (population: 776) in the east, and the rest of the municipality (population: 2,030) remained as Hemne. 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 Vinje (population: 576), Hemne (population: 2,325), and the western part of the municipality of Heim (population: 711) were merged to form a new, enlarged municipality of Hemne.^[3]

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.^[5]
