Olof Möller (July 3, 1923, Riga – June 8, 1985, Solna) was a Swedish science fiction author. He is thought to be the most prolific Swedish science fiction writer, though most of his writing can be classified as pulp. He published 30 pocket books in the Jaktrymdskepp X12 ("Fighter Starship X12") series between 1974 and 1980. Möller was born in Riga, Latvia, the son of medical practitioner and scientist Maximilian Möller and the German-born author Camilla Möller. The family fled to Sweden in 1939. Möller graduated from the Stockholm Institute of Commerce in 1941.
