Enemy Unseen is a Star Trek: The Original Series novel written by V.E. Mitchell.

The novel was originally set before "Where No Man Has Gone Before", but had to be rewritten at a late stage to be set after Star Trek: The Motion Picture, due to Paramount insisting that the Deltans were not part of the United Federation of Planets in that era.
