Science Fiction Quarterly was an American pulp science fiction magazine that was published from 1940 to 1943 and again from 1951 to 1958. Charles Hornig served as editor for the first two issues; Robert W. Lowndes edited the remainder. Science Fiction Quarterly was launched by publisher Louis Silberkleit during a boom in science fiction magazines at the end of the 1930s. Silberkleit launched two other science fiction titles (Science Fiction and Future Fiction) at about the same time: all three ceased publication before the end of World War II, falling prey to slow sales and paper shortages. In 1950 and 1951, as the market improved, Silberkleit relaunched Future Fiction and Science Fiction Quarterly. By the time Science Fiction Quarterly ceased publication in 1958, it was the last surviving science fiction pulp.
