Gentleman's Agreement is a 1947 novel by Laura Z. Hobson which explored the problem of antisemitism in the United States, what The New York Times called, in a contemporary review, "a story of the emotional disturbance that occurs within a man who elects, for the sake of getting a magazine article, to tell people that he is a Jew and who experiences first-hand, as a consequence, the shock and pain of discriminations and social snubs.

The novel tells the story of Philip Green, new staff writer for a national magazine.

This ruse causes problems with his fiancée, who is a social climbing suburbanite and divorcée.

The book received rave reviews, with The New York Times Book Review calling it "required reading for every thoughtful citizen in this perilous century".

The Philadelphia Inquirer said it "bids fair to being one of the most astonishing novels of the year", and it was republished as an Armed Services Edition later in 1947.
