Two Complete Science-Adventure Books was an American pulp science fiction magazine, published by Fiction House, which lasted for eleven issues between 1950 and 1954 as a companion to Planet Stories. Each issue carried two novels or long novellas. It was initially intended to carry only reprints, but soon began to publish original stories. Contributors included Isaac Asimov, Robert A. Heinlein, Arthur C. Clarke, Poul Anderson, John Brunner, and James Blish. The magazine folded in 1954, almost at the end of the pulp era.
