The 1,092-square-kilometre (422 sq mi) municipality is the 103rd largest by area out of the 357 municipalities in Norway. Karlsøy is the 268th most populous municipality in Norway with a population of 2,237. The municipality'spopulation density is 2 inhabitants per square kilometre (5.2/sq mi) and its population has decreased by 4.2% over the previous 10-year period.[6][7]
Karlsøy has been aChurch of Norwayparish for many years. Many immigrants, mostly from Finland, resided in Karlsøy as evidenced by the 1801 census.[8] The analysis of the census data revealed that the family names of these people such as Aderup,Blix andRosenlund were foreign-sounding.[8]
Theparish of Karlsøy was established as a municipality on 1 January 1838 (see theformannskapsdistrikt law). On 1 January 1867, the southern district of Karlsøy (population: 862) was transferred from Karlsøy to the neighboringLyngen Municipality (that area later became part ofUllsfjord Municipality). On 1 September 1886, the western island district of Karlsøy (population: 828) was separated from Karlsøy to become the newHelgøy Municipality. This left Karlsøy with 1,334 inhabitants.
During the 1960s, there were many municipal mergers across Norway due to the work of theSchei Committee. On 1 January 1964,Helgøy Municipality was merged back into Karlsøy Municipality. At the same time, all of the mainland areas of Karlsøy (the northern part of the Lyngenpeninsula, with 1,001 inhabitants) was transferred from Karlsøy to neighboringLyngen Municipality. After all the changes, the new Karlsøy had 3,414 residents. On 1 January 2008, the southern part of the island ofReinøya was transferred fromTromsø Municipality to Karlsøy Municipality.[9][10]
On 1 January 2020, the municipality became part of the newly formedTroms og Finnmark county. Previously, it had been part of the oldTroms county.[11] On 1 January 2024, theTroms og Finnmark county was divided and the municipality once again became part ofTroms county.[12]
The municipality (originally theparish) is named after the smallKarlsøya island (Old Norse:Kalsøe) since the firstKarlsøy Church was built there. The first element is thegenitive case of the male nameKarl. The last element isøy which means "island".[13] Historically, the name of the municipality was spelledKarlsø. On 6 January 1908, aroyal resolution changed the spelling of the name of the municipality toKarlsøy. The lettery was added to the end of the word to "Norwegianize" the name (ø is the Danish word for "island" andøy is the Norwegian word).[14]
Thecoat of arms was granted on 12 December 1980. The officialblazon is"Azure, an eagle headerasedargent" (Norwegian:I blått et avrevet sølv ørnehode). This means the arms have a bluefield (background) and thecharge is the head of awhite-tailed eagle. The eagle head has atincture ofargent which means it is commonly colored white, but if it is made out of metal, then silver is used. The blue color in the field symbolizes the importance of the sea to the island community. The eagle head was chosen since one ofEurope's largest colonies of these birds is found on the island ofNord-Fugløya in the municipality. Furthermore, the eagle symbolizes the importance offishing for the municipality. The arms were designed by Hallvard Sandvik.[15][16][17]
Karlsøy is among the world's most importantexporters ofdried and salted cod, withPortugal,Spain, andBrazil among the main markets.[citation needed] The population is almost totally dependent on fishing.[citation needed] There are also goat herding businesses and some musicians that live on the island. There is also some tourism, including a festival that runs in the Summer. There are plans for 50 holiday homes to be built on the isle.[citation needed]
The municipality consists of islands only.Ringvassøya, Norway's sixth largest island, is the largest island in the municipality.Nordkvaløya,Helgøya,Karlsøya,Vannøya,Reinøya, andRebbenesøya are the other major islands. The highest point in the municipality is the 1,049.3-metre (3,443 ft) tall mountainSoltindan on the island of Ringvassøy.[1]
The islands of Rebbenesøya and Ringvassøya are split (as was Reinøya before 2008), with the southern part belonging to neighboringTromsø Municipality. The reason is that the borders were drawn when boat was the only means of transportation; then it made sense that the southern parts of the islands belonged to Tromsø while the northern parts belonged to Karlsøy. Today, when roads have replaced the boats, the situation is different which is why the Norwegian government transferred all of the island of Reinøy to the Karlsøy Municipality on 1 January 2008.[10]
The island ofHelgøya, the former seat of the oldHelgøy Municipality, in the western part of Karlsøy Municipality, is today a more or less an abandoned village of wooden houses and the oldHelgøy Church. The island can only be reached when services are celebrated in the church, and ferry rides are organized.
LakeSkogsfjordvatn, in the centre ofRingvassøya, is a lake with some fishing, surrounded by sub-Arcticforests. This is Norway's largest lake in an island. The island ofVannøya has several villages, including Burøysund andTorsvåg, the latter offering views of theAtlantic from theTorsvåg Lighthouse.
Karlsøy mostly has a cool oceanic climate (subpolar oceanic climate) using the -3°C isotherm, or a very mildsubarctic climate using the 0°C isotherm. Spring and summer is the driest season, while autumn and winter is much wetter. Torsvåg lighthouse has been recording temperature since 1933, and is situated on the northwestern tip of Vanna island. The eastern and inland part of the islands will have slightly warmer summers and slightly colder winters. The record low at Torsvåg is −15.1 °C (4.8 °F) recorded January 1979. The record high 27.2 °C (81.0 °F) is from July 1966. The average date for the last overnight freeze (low below 0 °C (32.0 °F)) in spring is 6 May[18] and average date for first freeze in autumn is 25 October[19] giving a frost-free season of 171 days (1981-2010 average for Torsvåg).

The municipal centre is at Hansnes, which can be reached through anundersea tunnel from Tromsø, and the drive is about one hour. From hereferries depart to Vannøya, Reinøya, and Karlsøya. TheLangsund Tunnel is under construction and was planned to be completed by 2015, but it is currently on hiatus. It is expected to connect the islands ofReinøya andRingvassøya. The few inhabitants of Rebbenesøya are served by a ferry from Mikkelvik on the western side of Ringvassøya.
There is a flat highplateau on Nordfugløya, 600 m (2,000 ft) above sea level, whereArcticcloudberries grow. The island can only be reached in thecloudberry season, when picking expeditions are organized from Burøysund.
