Chimera is a 1972 fantasy novel written by American writer John Barth, composed of three loosely connected novellas. The novellas are Dunyazadiad, Perseid and Bellerophoniad, whose titles refer eponymously to the mythical characters Dunyazad, Perseus and Bellerophon. The book is an example of postmodernism, which can be seen in its metafictional content and its incorporation of stylistic elements that go beyond the traditional novel genre. It shared the U.S. National Book Award for Fiction with Augustus by John Edward Williams.

John Simmons Barth was an American writer best known for his postmodern and metafictional fiction. His most highly regarded and influential works were published in the 1960s, and include The Sot-Weed Factor, a whimsical retelling of Maryland's colonial history; Giles Goat-Boy, a satirical fantasy in which a university is a microcosm of the Cold War world; and Lost in the Funhouse, a self-referential and experimental collection of short stories. He was co-recipient of the National Book Award in 1973 for his episodic novel Chimera.
