Red Harvest is a seminal novel by Dashiell Hammett, first published in 1929. It is narrated by The Continental Op, a recurring character in Hammett's world. The novel has had a great deal of influence on later fiction ranging from samurai films to noir.

Red Harvest is thought to have been an influence on Akira Kurosawa's film Yojimbo, and combined with The Glass Key is a heavy influence on Coen Brothers's noir film Miller's Crossing. Red Harvest also coined the term Blood Simple (after which the Coen Brothers' film debut is named); the phrase refers to the addled, fearful mindset people are in after a prolonged immersion in violent situations.

Red Harvest is not related to Blue Harvest: Horror Beyond Imagination.
