The Grapes of Wrath is an American realist novel written by John Steinbeck and published in 1939. The book won the National Book Award and Pulitzer Prize for fiction, and it was cited prominently when Steinbeck won the Nobel Prize in 1962.

Set during the Great Depression, the novel focuses on the Joads, a poor family of tenant farmers driven from their Oklahoma home by drought, economic hardship, agricultural industry changes and bank foreclosures forcing tenant farmers out of work. Due to their nearly hopeless situation, and in part because they were trapped in the Dust Bowl, the Joads set out for California. Along with thousands of other "Okies", they sought jobs, land, dignity, and a future.
