Axel Heiberg (16 March 1848 – 4 September 1932) was a Norwegian diplomat, financier and patron, born in Kristiania.
He was married to Ragnhild Meyer, daughter of Thorvald Meyer. They had one child, Ingeborg, who married N. O. Young Fearnley.
Heiberg studied abroad and, after a period as Norwegian consul in China, returned to Norway, where he financed the creation of the Ringnes brewery in 1876 together with the brothers Amund Ringnes (brewer) and Ellef Ringnes (administrator and salesman).
Together with the shipowner Thomas Fearnley, the brewery sponsored the polar expeditions of Fridtjof Nansen and Otto Sverdrup, and funded the construction of the exploration vessel Fram. This led to Heiberg's name being given to Axel Heiberg Island in Canada, the Axel Heiberg Glacier in Antarctica, and the Geiberg Islands in Siberia.
In 1878 Heiberg was one of the founders of the rowing club Christiania RK. Later he founded the "Consul Axel Heiberg and Manufacturer Hans B. Fasmer Fund" (in 1915 transferred to the Fridtjof Nansen Fund). In 1898 he was one of the founders of the Norwegian Forestry Society, and was chairman until 1923. He also funded the statues of Henrik Ibsen and Bjørnstjerne Bjørnson outside the National Theater in Oslo.
Axel Heiberg (1908–1988) was a Norwegian judge.
He was a son of barrister Axel Heiberg (1875–1952), brother of Bernt and Edvard Heiberg, nephew of Eivind Heiberg, first cousin of Hans Heiberg and a first cousin once removed of Gustav, Jacob, Gunnar and Inge Heiberg.
He worked as a lawyer from 1935, and became a prosecutor in Oslo District Court in 1946. He was also working with the legal purge in Norway after World War II, and was involved in the Norwegian Bar Association.
In 1952 he was named as a Supreme Court Justice, and he stood in this position until his retirement in 1978. He also served as leader of the Norwegian Association of Judges, and co-founded and edited the academic journal Lov og Rett. He died in 1988.
