Kvalsund (Northern Sami: Fálesnuorri and Kven: Valasnuora) is a former municipality in Finnmark county in Norway.

On 1 January 1963, the Kokelv area in southern Måsøy Municipality (population: 34) was transferred to Kvalsund.

The official blazon is "Azure, three salmon argent in pall heads to center" (Norwegian: I blått tre hvite lakser i trepass med hodene innover).

This means the arms have a blue field (background) and the charge is three salmon arranged in pall with their heads facing the centre.

The salmon have a tincture of argent which means they are commonly colored white, but if it is made out of metal, then silver is used.

The gakti of the Kvalsund region is easily recognizable by dots and jags on the collars (for men) and sleeves (for women).

The municipality hosts an annual rock festival known as Fægstock, which takes place in Fægfjord (Northern Sami: Veaigesvuotna, meaning "twilight fiord").

The municipal council (Kommunestyre) of Kvalsund was made up of 15 representatives that were elected to four year terms.

The Seilandsjøkelen glacier was partially located in Kvalsund, and at 986 metres (3,235 ft) in height, it was the highest point in the municipality.

Historically, that village was called Finnbyen, a name meaning simply "Coast Sámi settlement".
