Off the Main Sequence: The Other Science Fiction Stories of Robert A. Heinlein (ISBN 1-58288-184-7) is a collection of 27 short stories by American writer Robert A. Heinlein, including three that were never previously collected in book form.
The title is a play on the astronomy concept off the main sequence, and refers to these stories not being part of Heinlein's Future History.
