Etne is a municipality in Vestland county, Norway. It is located in the traditional district of Sunnhordland, although it is also sometimes considered to be part of the district of Haugaland. The administrative centre of the municipality is the village of Etnesjøen. Other villages in the municipality include Skånevik and Fjæra. The two largest villages in the municipality are Etnesjøen with 1,159 residents and Skånevik with 594 residents (all figures from 1 January 2015).

The 735-square-kilometre (284 sq mi) municipality is the 154th largest by area out of the 356 municipalities in Norway. Etne is the 201st most populous municipality in Norway with a population of 4,073. The municipality's population density is 5.8 inhabitants per square kilometre (15/sq mi) and its population has increased by 0.8% over the previous 10-year period.

Etne is situated south of the city of Bergen and it borders the municipalities of Kvinnherad, Ullensvang, Sauda, Suldal, and Vindafjord, the latter three are located in the neighboring county of Rogaland.

A Norwegian motion picture called United was shot in Etne with local people as actors.

Etne was established as a municipality on 1 January 1838 (see formannskapsdistrikt law). Originally, Etne encompassed the area around the Etnefjorden and the surrounding valleys. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1965, the neighboring municipality of Skånevik was dissolved and merged into its neighboring municipalities. All of Skånevik located south of the Åkrafjorden and east of the village of Åkra on the north side of the fjord (population: 1,493) was merged into Etne.

The municipality (originally the parish) is named after the Etnefjorden (Old Norse: Eðni). The name is likely derived from the old name for the river "Etneelvi", Atn or Etn. The meaning of the old river name may come from etja which means "to drive forward" or "to goad" or it might come from eta which means "to eat".

The coat of arms was granted on 16 December 1983. The official blazon is "Per pale dovetailed azure and argent" (Norwegian: Kløyvt av blått og kvitt med duestjertsnitt). This means the arms have are divided with a vertical line that is dovetailed. The field (background) to the left of the line has a tincture of blue. To the right of the line, the field has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used. The design was chosen to represent the strong unity between the two former municipalities of Skånevik and Etne that were joined to form one municipality in 1965. The arms were designed by Magnus Hardeland and John Digernes. The municipal flag has the same design as the coat of arms.

The Church of Norway has two parishes (sokn) within the municipality of Etne. It is part of the Sunnhordland prosti (deanery) in the Diocese of Bjørgvin.

Etne has a varied landscape, extending from the Etnefjorden, Skånevikfjorden, and Åkrafjorden at sea level, through the villages up to the high mountains. In the far north, there is a barren and heavily eroded mountain glacier, Folgefonna, where the municipality's highest point rises 1,638 metres (5,374 ft) above sea level. Folgefonna National Park is partially located in Etne. In addition to that national park, Etne has three nature reserves: Brattholmen, Skåno, and Langebudalen. Lakes in the area include Løkjelsvatnet. The famous waterfall Langfossen is located in northern Etne.

Recent archeological findings indicate that the area was already inhabited around 500 BC.
