The Eyes of Heisenberg is a 1966 science fiction novel by American writer Frank Herbert. Originally serialized as Heisenberg's Eyes in Galaxy magazine between June and August 1966, it was issued as a book by Berkley later the same year. The title refers to Werner Heisenberg's uncertainty principle, which the plot examines as a source of randomness both on the molecular (specifically genetic) level and on a macroscopic (anthropological) level.
