Botne is a former municipality in Vestfold county, Norway. The 85-square-kilometre (33 sq mi) municipality existed from 1838 until its dissolution in 1964. The area is now part of Holmestrand Municipality in the traditional district of Jarlsberg. The administrative centre was the village of Botne where the Botne Church is located. Other villages in the municipality included Hillestad and Gullhaug.

The parish of Botne was established as a municipality on 1 January 1838 (see formannskapsdistrikt law). The initial population of Botne Municipality was about 1,600 residents. In 1942, an area of Botne (population: 148) was transferred into the neighboring town of Holmestrand. In 1947, an area of Botne (population: 8) was transferred to the neighboring Våle Municipality. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, Botne Municipality (population: 4,656) was merged with the town of Holmestrand (population: 1,956) to form a new, larger Holmestrand Municipality.

The municipality (originally the parish) is named after the old Botne farm (Old Norse: Botnar) since the first Botne Church was built there. The name is the plural form of botn which means "bottom", "hollow", or "depression".

The Church of Norway had two parishes (sokn) within the municipality of Botne. At the time of the municipal dissolution, it was part of the Nord-Jarlsberg prosti (deanery) in the Diocese of Tunsberg.
