Carl Johan Fredrik Skottsberg (1 December 1880 – 14 June 1963) was a Swedish botanist and explorer of Antarctica.

[4] He was educated locally then studied Sciences at Uppsala University from 1898, specialising in Botany, and receiving his doctorate (PhD) there in 1907.

On his return to Sweden, Skottsberg published (1905) the first comprehensive phytogeographic study of the flora of southern Patagonia and Tierra del Fuego.

Carl Skottsberg is believed to have been the last to have seen the Santalum fernandezianum tree alive when he visited the Juan Fernández Islands in 1908.

Skottsberg was a member of the Royal Swedish Academy of Sciences and several other Swedish learned societies, and was elected a Fellow of the Royal Society in 1950.
