Oslo( , , ( or ; , , ) is the Capital city and most populous city of Norway. It constitutes both a county and a municipality. The municipality of Oslo had a population of in 2022, while the city's greater urban area had a population of 1,064,235 in 2022, and the metropolitan area had an estimated population of in 2021.
During the Viking Age, the area was part of Viken. Oslo was founded as a city at the end of the Viking Age in 1040 under the name Ánslo, and established as a kjobstad or trading place in 1048 by Harald Hardrada. The city was elevated to a bishopric in 1070 and a capital under Haakon V of Norway around the year 1300. with Denmark from Kalmar Union and again from 1536 to 1814 reduced its influence. After being destroyed by a fire in 1624, during the reign of King Christian IV, a new city was built closer to Akershus Fortress and named Christiania in honour of the king. It became a municipality ( formannskapsdistrikt) on 1 January 1838. The city functioned as the capital of Norway during the 1814–1905 union between Sweden and Norway. From 1877, the city's name was spelled Kristiania in government usage, a spelling that was adopted by the municipal authorities in 1897, although 'Christiania' was also used. In 1925, the city, after incorporating the village retaining its former name, was renamed 'Oslo'. In 1948, Oslo merged with Aker, a municipality which surrounded the capital and which was 27 times larger, thus creating the modern, much larger Oslo municipality.
Oslo is the economic and governmental centre of Norway. The city is also a hub of Norwegian trade, banking, industry and shipping. It is an important centre for maritime industries and maritime trade in Europe. The city is home to many companies within the maritime sector, some of which are among the world's largest shipping companies, shipbrokers and maritime insurance brokers. Oslo is a pilot city of the Council of Europe and the European Commission intercultural cities programme.
Oslo is considered a global city and was ranked "Beta World City" in studies carried out by the Globalization and World Cities Study Group and Network in 2008. It was ranked number one in terms of quality of life among European large cities in the European Cities of the Future 2012 report by fDi magazine. A survey conducted by ECA International in 2011 placed Oslo as the second most expensive city in the world for living expenses after Tokyo. In 2013, Oslo tied with the Australia city of Melbourne as the fourth most expensive city in the world, according to the Economist Intelligence Unit (EIU)'s Worldwide Cost of Living study. Oslo was ranked as the 24th most liveable city in the world by Monocle magazine.
Oslo's population was increasing at record rates during the early 2000s, making it the fastest growing major city in Europe at the time. This growth stems for the most part from international immigration and related high birth rates, but also from intra-national migration. By 2010 the immigrant population in the city was growing somewhat faster than the Norwegians population, and in the city proper this had become more than 25% of the total population if the children of immigrant parents were included.
To the north and east, wide forested hills ( Marka) rise above the city giving the location the shape of a giant amphitheatre. The urban municipality ( bykommune) of Oslo and county ( fylke) of Oslo are two parts of the same entity, making Oslo the only city in Norway where two administrative levels are integrated. Of Oslo's total area, is built-up and is agricultural. The open areas within the built-up zone amount to .
The city of Oslo was established as a municipality on 3 January 1838 (see formannskapsdistrikt). It was separated from the county of Akershus to become a county of its own in 1842. The rural municipality of Aker was merged with Oslo on 1 January 1948 (and simultaneously transferred from Akershus county to Oslo county). Furthermore, Oslo shares several important functions with Akershus county.

The Old Town is an area within the administrative district Gamle Oslo. The previous names are reflected in street names like Oslo gate (Oslo street)

Erroneously, it was once assumed that Oslo meant "the mouth of the Lo river", a supposed previous name for the Alnaelva. Not only has no evidence been found of a river "Lo" predating the work where Peder Claussøn Friis first proposed this etymology, but the very name is ungrammatical in Norwegian: the correct form would have been Loaros (cf. Nidaros). The name Lo is now believed to be a back-formation arrived at by Friis in support of his idea etymology for Oslo. "Alna – elv i Oslo" , In: Store Norske Leksikon (in Norwegian).
According to the Norse , Oslo was founded around 1049 by Harald Hardrada. Recent archaeological research, however, uncovered Christian burials which could be dated to prior to AD 1000, evidence of a preceding urban settlement. This called for the celebration of Oslo's millennium in 2000 rather than 2049.
In 1174, Hovedøya Abbey was built. The churches and abbeys became major owners of large tracts of land, which proved important for the city's economic development, especially before the Black Death.
At the end of the 12th century, Hanseatic League traders from Rostock moved into the city and gained major influence in the city.
On 25 July 1197, Sverre of Norway and his soldiers attacked Oslo from Hovedøya.
During the Middle Ages, Oslo reached new heights during the reign of Haakon V of Norway (1299–1319). He was the first king to reside permanently in the city, and it has been regarded as the capital city of Norway since his reign. He also started the construction of the Akershus Fortress and the Oslo Kongsgård.
The Black Death came to Norway in 1349 and, like other cities in Europe, the city suffered greatly. The churches' earnings from their land dropped so much that the Hanseatic traders dominated the city's foreign trade in the 15th century.
In 1380, Norway was the weaker part in a personal union with Denmark, and Oslo's role was reduced to that of provincial administrative centre, with the monarchs residing in Copenhagen.
The transformation of Christiania went slowly for the first hundred years. However, outside of the city at Vaterland, Grønland, and the old town of Oslo, a new, unmanaged part of the city arose populated by citizens of lower class status.
The last Black Death outbreak in Oslo occurred in 1654.
Large areas of the surrounding Aker municipality were incorporated in 1839, 1859, and 1878. The 1859 expansion included Grünerløkka, Grønland, and Oslo. At that time the area called Oslo (now Gamlebyen or Old Town) was a village or suburb outside the city borders east of Aker river.Boye, Else: Christiania 1814–1905. Oslo: Grøndahl, 1976. The population increased from approximately 10.000 in 1814 to 230.000 in 1900. In 1850, Christiania overtook Bergen and became the most populous city in the country. Christiania expanded its industry from 1840, most importantly around Akerselva. There was a spectacular building boom during the last decades of the 19th century, with many new apartment buildings and renewal of the city center, but the boom collapsed in 1899.
In 1877 the city was renamed Kristiania.
The municipality developed new areas such as Ullevål garden city (1918–1926) and Torshov (1917–1925). City Hall was constructed in the former slum area of Vika from 1931 to 1950. In 1948, Oslo merged with Aker, a municipality which surrounded the capital and was 27 times larger, thus creating the modern, vastly enlarged Oslo municipality. At the time, Aker was a mostly affluent, green suburban community, and the merger was unpopular in Aker. Other suburbs, such as Lambertseter, began to be developed in the 1950s. Aker Brygge was constructed on the site of the former shipyard, Aker ASA, from 1982 to 1998.
Norway was invaded by Germany on 9 April 1940. Efforts to stop the invasion, most notably the sinking of the Blücher, delayed the occupation of Oslo for several hours which allowed King Haakon to escape the city. Oslo remained occupied throughout the war until Germany capitulated in 1945. During this time, the occupying troops were harried by saboteurs in acts of resistance. On 31 December 1944, allied bombers missed their intended target and hit a tram, resulting in 79 civilian deaths.
During the 2011 Norway attacks, Oslo was hit by a bomb blast that ripped through the Government Quarter, damaging several buildings including the building that houses the Office of the Prime Minister. Eight people died in the bomb attack.
On 25 June 2022, two people were killed and 21 others injured in a mass shooting. An Iranian-born Norwegian citizen was subsequently charged with "aggravated terrorism".
The city has continued to expand. For a few years, new large scale housing areas and infrastructure projects are being built and planned across the city, notably in Hasle, Helsfyr,Bjørvika, Nydalen and Sinsen, this is increasing the density in and around Ring 2 and Ring 3. The Fornebu Line on the metro is under construction as of 2024, and further subway lines crossing the inner city are being planned.
Although Eastern Norway has a number of rivers, none of these flow into the ocean at Oslo. Instead Oslo has two smaller rivers: Akerselva (draining Maridalsvannet, which flows into the fjord in Bjørvika), and Alna River. The waterfalls in Akerselva gave power to some of the first modern industry of Norway in the 1840s. Later in the century, the river became the symbol of the stable and consistent economic and social divide of the city into an East End and a West End; the labourers' neighbourhoods lie on both sides of the river, and the divide in reality follows Uelands street a bit further west. River Alna flows through Groruddalen, Oslo's major suburb and industrial area. The highest point is Kirkeberget, at . Although the city's population is small compared to most European capitals, it occupies an unusually large land area, of which two-thirds are of forests, hills and lakes. Its boundaries encompass many parks and open areas, giving it an airy and green appearance.
The warmest month on record is July 1901 with mean , and the all-time high was also recorded in July 1901. The warmest month in more recent years is July 2018 with mean and average daily high . The record summer of 2018 also recorded the warmest May and May all-time high with on 30th, and 2018 was even the sunniest year on record with 2133 sunhours. On 27 July 2018, the temperature in Oslo rose to , the hottest recorded since 1937, when weather recordings started at Blindern. In January, on average three out of four days are below freezing () and one out of four days is colder than (1961–1990). The coldest temperature recorded is , on 21 January 1841, while the coldest recorded at Blindern is in January 1941. The coldest temperature more recently was on 6 January 2024, where the temperature reached -23.1 °C (-17 °F) at Oslo-Blindern, which is the coldest measured temperature since January 1987. The coldest month on record is January 1941 and also January 1947 with mean and average daily low . The average date for the last overnight freeze (low below ) in spring is 23 April and average date for first freeze in autumn is 17 October giving a frost-free season of 176 days (1981–2010 average for Blindern). Oslo sits right on the border between hardiness zones 7a and 7b.
Oslo Gardermoen airport is located 35 km northeast of Oslo and has a humid continental climate (Köppen climate classification: Dfb) bordering on a subarctic climate (Köppen climate classification: Dfc).
The municipality operates eight public swimming pools. Tøyenbadet is the largest indoor swimming facility in Oslo and one of the few pools in Norway offering a 50-metre main pool. Another in that size is the outdoor pool Frognerbadet.
When Christiania was made capital of Norway in 1814, there were practically no buildings suitable for the many new government institutions. An ambitious building program was initiated, but realised very slowly because of economic constraints. The first major undertaking was the Royal Palace, designed by Hans Linstow and built between 1824 and 1848. Linstow also planned Karl Johans gate, the avenue connecting the Palace and the city, with a monumental square halfway to be surrounded by buildings for Oslo University, the Stortinget (Storting) and other institutions. Only the university buildings were realised according to this plan. Christian Heinrich Grosch, one of the first architects educated completely within Norway, designed the original building for the Oslo Stock Exchange (1826–1828), the local branch of the Bank of Norway (1828), Christiania Theatre (1836–1837), and the first campus for the University of Oslo (1841–1856). For the university buildings, he sought the assistance of the German architect Karl Friedrich Schinkel. German architectural influence persisted in Norway, and many wooden buildings followed the principles of Neoclassicism. In Oslo, the German architect Alexis de Chateauneuf designed Trefoldighetskirken, the first neo-gothic church, completed by von Hanno in 1858.
A number of landmark buildings, particularly in Oslo, were built in the Functionalist style (better known in the US and Britain as Modernist), the first being (1925–1927) by Lars Backer, demolished in 1970. Backer also designed the restaurant at Ekeberg, which opened in 1929. Kunstnernes Hus art gallery by Gudolf Blakstad and Herman Munthe-Kaas (1930) still shows the influence of the preceding classicist trend of the 1920s. The redevelopment of Gardermoen (by the Aviaplan consortium) at Gardermoen, which opened in 1998, was Norway's largest construction project to date.
