Star Bridge is a science fiction novel by American authors Jack Williamson and James E. Gunn. It was published in 1955 by Gnome Press in an edition of 5,000 copies. However, 900 copies were never bound. It was also issued in paperback by Ace (D-169, 1955, 35¢, and F-241, 40¢) and reissued by Berkley Books in 1977 and by Ballantine Books in 1982 (with minor typographic errors). It is an adventure story in the classic Williamson tradition, woven with a reflection about the relative importance of impersonal forces and individuals in the events of history.
