Tom Joad is the central character in which novel?

'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 was awarded 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 are trapped in the Dust Bowl, the Joads set out for California. Along with thousands of other "Okies", they seek jobs, land, dignity, and a future.

Tom Joad is the protagonist of the story, the second son of the Joad family, named after his father.
