The World Wreckers is a science fantasy novel by American writer Marion Zimmer Bradley, part of her Darkover series.

First published by Ace Books in 1971, it features a complex sub-plot involving the sexual interactions between hermaphrodite native species, known as the chieri, and humans.

The mysterious Andrea Closson accepts a contract to wreck the economy of Darkover, so that the planet must turn to the Terran Empire for assistance.

He learns that her grandmother was Desideria Leynier-Storn, the leronis who raised Sharra to restore High Windward to its rightful family (as seen in The Winds of Darkover).

Citizens from all over Darkover apply to Regis for assistance, describing economic problems, crop failures, and fires.

During a festival dance, their minds join in ecstasy and call into the castle the form of Andrea Closson, whom one of the chieri identifies as a lost member of his people.

She is able to find hope in her people's survival in Keral's child with Project Telepath member David Hamilton, a union such as resulted in the strain of the Comyn.
