The Abysmal Brute is a novel by American writer Jack London, first published in book form in 1913. It is a short novel, and could be regarded as a novelette. It first appeared in September 1911 in Popular Magazine.

In the story, a successful boxer, who was brought up in a log cabin and knows little of the real world, begins to realize the corrupt practices in the game of boxing.Sam Stubener, a boxing manager in San Francisco, travels to a remote log cabin in northern California on getting a letter from retired boxer Pat Glendon, who lives there with his son, Pat Glendon Jr, a promising young boxer. Pat Jr fights well; otherwise, he knows little of city life; he hunts and fishes in the forest, he reads poetry and avoids women.

Sam brings Pat Jr back to San Francisco. Although Sam and Pat both know he could win a fight with a top boxer, the conventions of boxing require that Pat has to start with a boxer of lower rank. In his first three fights, he knocks out his opponent immediately with one punch. Sam tells Pat to make his fights last longer; since Pat says that he is master of his opponent "at any inch or second of the fight", they agree on which round the knockout will happen.

Pat's career takes off, winning fights worldwide. The newspapers, who interpret his detachment from the real world as unsociability, call him "The Abysmal Brute." Sam protects him from the corruption in boxing. Pat is not aware that Sam is using his knowledge of the timing of the knockout in a betting syndicate.

Pat is interviewed by Maud Sangster, a journalist from a family of millionaires, at the Cliff House, San Francisco. They immediately fall in love. Maud tells him she has heard in which round he will knock out his opponent in his next fight, and Pat wonders how his agreement with Sam became known. He tells her the knockout will be in a later round; this is to be a secret. When his opponent is knocked out in the round originally agreed with Sam, Maud is angry with Pat. He tells her his opponent faked the knockout; he is beginning to realize the corruption in the game, and says he is quitting boxing, although Sam has arranged a fight against top boxer Tom Cannam.

Pat and Maud get married; their honeymoon is spent in the forest and mountains. He decides to return for the fight with Cannam. The event, promoted as an important occasion, starts with speeches from boxing legends to which, unexpectedly, he adds his own, describing the corruption in boxing. This has a sensational effect; he then knocks out Cannam in the first round, and the event ends in uproar.
