Adventures in Time and Space is an American anthology of science fiction stories edited by Raymond J. Healy and J. Francis McComas and published in 1946 by Random House. A second edition was also published in 1946 that eliminated the last five stories. A Modern Library edition was issued in 1957. When it was re-released in 1975 by Ballantine Books, Analog book reviewer Lester del Rey referred to it as a book he often gave to people in order to turn them onto the genre. It is now once again out of print.
