Better Than Life is a science fiction comedy novel by Grant Naylor, the collective name for Rob Grant and Doug Naylor, co-creators and writers of the Red Dwarf television series, on which the novel is based. The main plotline was developed and expanded from the Red Dwarf episode of the same name, as well as the Series 3 and 4 episodes: White Hole, Marooned, Polymorph, and Backwards.

The book, first published 1990, is a sequel to Red Dwarf: Infinity Welcomes Careful Drivers, and was the first Red Dwarf novel to receive its first print run in hardback edition. Like the first novel, Better Than Life became a best seller and was reproduced in paperback, omnibus and audiobook versions. Two further novels, Last Human and Backwards, were each created as alternate sequels by the writers, and followed in 1995 and 1996 respectively.
