Hammerfest (; Hámmerfeasta ˈhaːmmerˌfea̯sːta) is a municipality in Troms og Finnmark county, Norway. Hammerfest is the northernmost town in the world with more than 10,000 inhabitants with the administrative centre of the municipality being the town of Hammerfest. Some of the main villages in the municipality include Rypefjord, Kvalsund, Forsøl, Hønsebybotn, Akkarfjord i Kvaløya, Akkarfjord i Sørøya, and Kårhamn. The municipality is the 19th largest by area out of the 356 municipalities in Norway. Hammerfest is the 102nd most populous municipality in Norway with a population of 11,274. The municipality's population density is and its population has increased by 3% over the previous 10-year period. The municipality encompasses parts of three large islands: Kvaløya, Sørøya, and Seiland. Other small islands such as Håja, Lille Kamøya and Kamøya are also located here. Most parts of the municipality do not have a road connection with the rest of Norway; only Kvaløya island is connected to the mainland, via the Kvalsund Bridge. A municipality called Hammerfest by og landdistrikt (Hammerfest town and district) was established on 1 January 1838 (see formannskapsdistrikt law), which included the town of Hammerfest and the vast rural district surrounding it. The law at that time required that all towns should be separated from their rural districts, but because of low population and very few voters, this was impossible to carry out for Hammerfest in 1838. (This was also the case in the nearby towns of Vadsø and Vardø.) In 1839, the northern district (population: 498) was separated to become a new municipality of Maasø. This left Hammerfest by og landdistrikt with 2,024 residents. On 1 January 1852, the rural district outside of the town (population: 1,256) was separated from the town to form a new municipality of Hammerfest landdistrikt. This left the town with 1,125 residents. (The rural district was later divided into two municipalities with Sørøysund in the north and Kvalsund in the south.
