The Killing Star is a hard science fiction novel by American writers Charles R. Pellegrino and George Zebrowski, published in April 1995.

It chronicles a sudden alien invasion in a late 21st century technological utopia, while covering several other speculative fiction ideas such as sublight interstellar travel, genetic cloning, virtual reality, advanced robotics, etc.

Anti-matter driven Valkyrie rockets carry explorers to the stars at nearly the speed of light.

They hide close to the Sun, inside asteroids, beneath the crusts of moons, within ice rings, and in interstellar space.

The Killing Star makes several references to historic and contemporary people, places, and things.
