Arnstein Rynning Arneberg (born July 6, 1882, in Halden, died June 9, 1961, in Biri) was a Norwegian architect. He was the child of Mauritz Otto Edvard Arneberg and Hermine Nicoline Mathilde Rynning, and the brother of Eilif Arneberg. He was first married to Aagot Kielland Skavlan (1888–1960), daughter of Olaf Skavlan, and later to Eva Elisabeth Reimers (1901–1987).

Arneberg served as an assistant to architect Alfred Christian Dahl in Oslo from 1898 to 1900. Between 1899 and 1902, he was a student at the Royal Drawing School in Oslo under Herman Schirmer. He worked as an assistant to Ole Sverre in Oslo from 1900 to 1903, and then under Gustaf Lindgren in Stockholm until 1906. Additionally, he studied under professors such as Isak Gustaf Clason and Erik Lallerstedt at the Royal Institute of Technology in Stockholm from 1904 to 1906.

After establishing his own practice in Oslo in 1906, Arneberg received numerous architectural commissions. Among his early works are the Eidsvoll Folk High School (1908) in Nordic panel style (demolished in 1980), railway stations on the Dovre Line (1912), and the Norwegian Seamen's Church in Rotterdam (1914). Together with Magnus Poulsson, he won the architectural competition for Oslo City Hall (1916–1918). They also won the competition for the Telegraph Building in Oslo (Kongens gate 21) in the same year. At its inauguration in 1924, it was Norway's third-largest building. The Viking Ship Museum on Bygdøy had its first wing opened in 1926.

In 1927, he was one of the artists and architects invited by Arno Berg, then the city conservator of Oslo, to propose ideas on how the capital's building stock could become more colorful and inviting. The initiative for this urban development project came from the artist Henrik Sørensen.
