Fusa (Urban East Norwegian: [ˈfʉ̂ːsɑ]) is a former municipality in the old Hordaland county, Norway.

Other villages in the municipality include Fusa, Holdhus, Holmefjord, Vinnes, Strandvik, and Sundvord.

The Frank Mohn company's Fusa marine division is headquartered here, with almost 500 employees.

The Bogstrand area of Fusa, located on the west side of the Fusafjorden (population: 28) was transferred to the municipality of Os.

On 3 November 1917, a royal resolution changed the spelling of the name of the municipality to Fusa.

The official blazon is "Argent, three gurges azure in pall" (Norwegian: På kvit grunn tre blå spiralar stilte i trepass).

The spirals also symbolise the many giant's kettles (Norwegian: jettegryte) in the municipality, which were created by the water in the rocks.

The municipal council (Kommunestyre) of Fusa was made up of 21 representatives that are elected to four year terms.
