Barna Hedenhös (The Hedenhös Children) is the name of a series of Swedish children's books in the 1950s written by Bertil Almqvist. The story is set in the Stone Age and follows the Hedenhös family. Barna Hedenhös is mostly known as a book series, but Almqvist also made an (albeit limited) animated television series about the Hedenhös family that was broadcast on SVT in 1972. Additionally, Almqvist made a comic version of the Hedenhös books for the comic book Tuff och Tuss during the 1950s; the comic version was later remade for the Pelle Svanslös children's comic book in the 1970s.
