The official blazon is "Per pale dovetailed azure and argent" (Norwegian: Kløyvt av blått og kvitt med duestjertsnitt).

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.

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.
