Porsanger (Northern Sami: Porsáŋgu; Kven: Porsanki[5]) is a municipality in Finnmark county, Norway.

Other villages in the municipality include Børselv, Brenna, Indre Billefjord, Kistrand, Olderfjord, and Skoganvarre.

[8] On 1 January 2020, the municipality became part of the newly formed Troms og Finnmark county.

Another theory is that the first element is derived from the Northern Sami word borsi which means "waterfall".

The official blazon is "Gules, three reindeer salient argent" (Norwegian: På rød bunn tre springende hvite rein).

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

Instead, the local people historically farmed reindeer, which is still an importance source of income for the residents.

The municipal council (Kommunestyre) of Porsanger is made up of 19 representatives that are elected to four year terms.

There are many smaller villages spread around the fjord on both sides, notably Kistrand, Olderfjord, Børselv, and Indre Billefjord.

Stabbursdalen National Park, with the world's northernmost pine forest, lies just west of the fjord and the village of Lakselv.

In Porsanger, there is midnight sun from 16 May until 27 July each year and there is polar night from 25 November to 16 January.

During spring, thousands of red knots stop to rest and feed along the shores of Porsangerfjord.

Lakselv has a boreal climate with modest precipitation and long winters, but still with annual mean well above freezing, ensuring there is no permafrost.

The weather station (recording since Aug 1945) is located at Banak Airport, 1 kilometre (0.62 mi) from the town.
