Oskar Eric Gunnar Hultén (18 March 1894 – 1 February 1981) was a Swedish botanist, plant geographer and 20th century explorer of The Arctic.
In his thesis, he coined the term Beringia for the ice-age land bridge between Eurasia and North America.
He published extensive accounts on the flora of several of these regions and distribution maps of thousands of species.
Hultén authored several botanical monographies on the Nordic area and from his travels in Siberia and the Aleutian Islands.
In 1973, he published his memoirs under the title Men roligt har det varit ("But it's been fun").
