Uppsala Tolkiensällskap is a Swedish Tolkien Society. Although based in Uppsala, it said to have branches all over Sweden, and other countries. It was founded in 1973 and is (as of March 2010) the second largest Tolkien Society in Sweden, having between 150-200 active members. The association is also known as Midgårds Fylking (roughly, "The Phalanx of Middle-earth"; "Fylking" also having the connotation of "Fylke", Åke Ohlmarks's Swedish translation in Härskarringen of the Shire). Uppsala Tolkiensällskap publishes Månrunan ("The Moon rune"), which is not available to non-members.
Uppsala Tolkiensällskap is not a literary association; it rather focuses on social gatherings and events. Unlike many other Tolkien Societies, Uppsala Tolkiensällskap is a secret and private society. Entering the association is only possible upon recommendation by a member.
