This category contains articles about the fiction Harry Turtledove contributed to the multi-author War World Series created by Jerry Pournelle. These stories deal with the CoDominium government on Earth and the politics of colonized planets.

War World should not be confused with the Worldwar franchise, a series written by Turtledove alone, dealing with the arrival of militaristic Lizard-like aliens on Earth in the middle of the 20th century.
