Åke Joel Ohlmarks (June 3, 1911 in Kristianstad, Sweden – 1984 in Crist di Niardo, Brescia, Italy) was a Swedish author, translator and scholar of religion.
Ohlmarks translation of J.R.R. Tolkien's The Lord of the Rings was strongly disliked by the author, prompting him to compile his Guide to the Names in The Lord of the Rings. Ohlmarks not just invented many expression of his own, but also took great liberties with the contents of Tolkien's work, both by shortening many parts of it and by inserting his own interpretations.
