''The Good Earth'' is a novel by Pearl S. Buck, first published in 1931. It won the Pulitzer Prize in 1932, and topped the best-seller lists in the United States for 1932 ''and'' 1933. It is the first, and much the best known, book in a trilogy which continues in ''Sons'' (1932) and ''A House Divided'' (1935). Though Buck was an American, she spent most of her early life in China, and ''The Good Earth'' is credited with doing much to humanise and demythologise China and Chinese people to Americans. By contrast, the book's unflinching depiction of some of the grimmer aspects of life in China have made it less than popular there.

The story concerns Wang Lung, a pre-revolutionary farmer who works his fingers to the bone to become successful with the help of his arranged-marriage wife O-Lan, only to drift away from his roots when he does achieve success.

''The Good Earth'' was adapted for the stage in 1932, and a film version was released in 1937. The film starred Paul Muni as Wang Lung. For her role as his wife O-Lan, Luise Rainer won an UsefulNotes/AcademyAward for Best Actress. The film also won the UsefulNotes/AcademyAward for Best Cinematography, and was nominated for Best Director, Best Film Editing and Best Picture. Despite Pearl Buck's objections, all the leading roles were given to white actors in {{yellowface}}.

!!Contains the following tropes:
* ArrangedMarriage: Two
* AttemptedRape: Wang Lung's nephew assaults his beautiful younger daughter. He's able to separate them before it can go any further, but the man's complete lack of remorse spurs him to marry the girl off as soon as possible.
* BeautyIsBad: Wang Lung's father specifically denies Wang Lung a beautiful woman, saying that a beautiful woman would not make a good wife to him and would only think of material things. He is ultimately right: a pampered, beautiful woman like Lotus with her bound feet would not have been able to work the fields with him. However, the pampered and beautiful Pear Blossom is a kind character who genuinely cares for Wang Lung and the "poor fool" in his old age.
* DeliberateValuesDissonance: Though Buck was a die-hard feminist, she depicts traditional Chinese practices (such as concubines and foot-binding) fairly straightforwardly.
* TheDiseaseThatShallNotBeNamed: O-Lan's illness, which she refers to as "a fire in my vitals": likely cancer.
* DownerEnding: [[spoiler: All the sympathetic characters are either dead or no longer sympathetic, Wang Lung has learned absolutely nothing and is just as much of a JerkAss - if not more - as when the novel started, and it's heavily implied that Wang Lung's sons are no better than he is, and they won't honor his wishes after his death.]]
* GenerationalSaga
* HollywoodMidLifeCrisis: Wang Lung has a massive one.
* ImAHumanitarian: Suspected of Wang Lung's aunt and uncle during a period of famine: They appear much better fed than their neighbors, and some of their children disappear and are never seen again.
** EatsBabies[=/=]OffingTheOffspring
* ImpoverishedPatrician: The House of Hwang, which is forced to sell most of their properties to Wang Lung
* JerkAss: Wang Lung to variable degrees, particularly his treatment of O-Lan. Many of the characters are none too kind.
* KarmicDeath: [[spoiler: Wang Lung's uncle and aunt die of an opium addiction. [[InvokedTrope Invoked]] because Wang Lung notices their addictions and sends his sons to give them more]].
* MayDecemberRomance: [[spoiler: Wang Lung and Pear Blossom]]
* MistakenForServant: Wang Lung realizes that he, in all respects still a peasant despite his great wealth, would look like a servant next to his well-dressed son. He doesn't like this realization.
* MoralityPet: Wang Lung develops some affection for his mentally handicapped daughter.
* NiceToTheWaiter: Subverted. When Wang Lung pulls a rickshaw, he gets a generous payment from a foreigner, but he soon realizes that she doesn't know how valuable the payment she gave was.
* NoNameGiven: Most characters in the narrative are not named, including all of Wang Lung's relatives and their spouses.
* ObliviousToLove: It's strongly implied in the novel that O-Lan has fallen in love with Wang Lung (a rarity in old fashioned arranged marriages, especially in China) but Wang Lung mistakes her devotion and obedience as slowness and stupidity, and repays her years of faithful servitude--and her having given birth to several sons, especially a first-born one--by falling in love with another woman, which breaks O-Lan's spirit.
* PerfectlyArrangedMarriage: Subverted. O-lan is indeed the perfect wife to Wang Lung, but since she is not beautiful Wang Lung can't love her.
* TheQuietOne: Wang Lung's third son.
* RagsToRiches
* SelfMadeMan: Wang Lung.
* ShamingTheMob: O-Lan manages to disperse an angry, starving mob who try to steal food from the equally poor and starving Wang Lung household.
* TheSociopath: Wang Lung's uncle.
* TheStoic: O-Lan
* TraitorShot: In the ending, [[spoiler: Wang Lung's sons pretend to agree to his LastRequest, but look at each other over his eyes and smile, indicating that they intend to go back on their word]].
* UntoUsASonAndDaughterAreBorn: The twins.
* {{Yellowface}}: The Chinese characters were played by white actors. Chinese American actress Anna May Wong wanted to play O-Lan; however, she was not allowed to play Paul Muni's wife, due to UsefulNotes/TheHaysCode's anti-miscegenation rule.
