Galactic Derelict is a science fiction novel by American writer Andre Norton, the second in her Time Traders series. It was first published in 1959, and as of 2012, had been reprinted in eight editions. It is part of Norton's Forerunner universe. Galactic Derelict continues the series' premise, an encounter between Western heroes and a mysterious alien race that has used time travel to alter Earth. This novel shifts between present day and the time of Folsom Man, some 10,000 years ago. In the 2000 republished version Norton changed the word Reds to Russians. No change was made in the story.
