"The Tactful Saboteur" is a science fiction novelette by American writer Frank Herbert, which first appeared in Galaxy Science Fiction magazine in October 1964. It is the second story in Herbert's ConSentiency universe (after "A Matter of Traces"), one of his three elaborate universes or franchises spanning multiple volumes (the others being the Dune universe and the Destination: Void universe developed with co-author Bill Ransom). The three chapter story "The Tactful Saboteur", written in a brisk, economical style, proved to be one of Herbert's most popular works. It was subsequently republished in The Worlds of Frank Herbert in 1971 and again in Herbert's 1985 short story collection Eye after interest was renewed in the wake of the film adaptation of Herbert's novel Dune.
