Frogner is a borough of the city of Oslo, Norway. In addition to traditional Frogner, the borough incorporates Bygdøy, Uranienborg and Majorstuen. The borough is named after Frogner Manor.

The borough is named after the old Frogner Manor. The Norse form of the name was Fraunar (plural form). The name is probably derived from the word frauð 'manure' - and then with the meaning 'fertilized fields'.

See also Frogn and Tøyen.

The area became part of the city of Oslo (then Christiania) in 1878. The borough was originally the ground and property of Frogner Manor, a splendid 18th century country estate now housing the Oslo City Museum. The Frogner Park (Frognerparken) includes the famous Vigeland Sculpture Park.

The major part of Frogner consists of houses built around 1900. Frogner was then a part of the city for the affluent, a status it has retained.

Traditional districts of Oslo belonging to the borough are:

On the Bygdøy peninsula are located the Viking ship Museum, Norsk Folkemuseum (Norwegian Museum of Cultural History), the Maritime Museum, the Kon-Tiki Museum and the ship Fram, used by Roald Amundsen for his Antarctic expedition. The royal estate Bygdøy kongsgård and the little palace of Oscarshall are also located here. Bygdøy is also a recreational area for Oslo's citizens with several public beaches.

Gustav Vigeland (11 April 1869 – 12 March 1943) was a Norwegian sculptor. Gustav Vigeland occupies a special position among Norwegian sculptors, both in the power of his creative imagination and in his productivity. He is most associated with Vigeland Sculpture Park (Vigelandsanlegget) in Oslo. He was also the designer of the Nobel Peace Prize medal.

Adolf Gustav Vigeland was born to a family of craftsmen, just outside Halse og Harkmark, a former municipality in Mandal. His parents were Elesæus Thorsen (1835–1886), a cabinetmaker and Anne Aanensdatter (1835–1907). His younger brother, Emanuel Vigeland, became a noted artist. As a youth, he was sent to Oslo where he learned wood carving at a local school. However, the sudden death of his father compelled him to move back to Mandal to help his family. Gustav lived for a time with his grandparents on a farm called Mjunebrokka in Vigeland, an old farm in Valle parish, Lindesnes municipality in Vest-Agder county.

He returned to Oslo in 1888, this time determined to become a professional sculptor. Vigeland came to the attention of sculptor Brynjulf Bergslien, who supported him and gave him practical training. The following year he exhibited his first work, Hagar and Ishmael.

Knut Nystedt (born 3 September 1915) is an orchestral and choral composer.

Nystedt was born in Kristiania (now Oslo), Norway, and grew up in a Christian home where hymns and classical music were an important part of everyday life.

Old church music, especially Palestrina and Gregorian chants, have had a major influence on his compositions.

He has studied with Aaron Copland, among others. Nystedt was organist in Torshov kirke (Torshov Church) in Oslo from 1946 to 1982 and taught choir conducting at the Universitetet i Oslo from 1964 to 1985.
