One-Armed Boxer (獨臂拳王) is a 1972 Hong Kong wuxia film directed, written by and starring Jimmy Wang Yu. Produced by Raymond Chow, it was released in 1972 in Hong Kong and various countries, and in late 1973 in the United States under a new title, The Chinese Professionals.

The film follows Yu Tien Lung (played by Wang Yu), a skilled Chinese martial artist whose martial arts school is targeted by a gang leader. After the various mercenary martial artists hired by the gang leader destroy his school, Tien, who lost his right arm in the battle, seeks revenge by strengthening his remaining arm beyond normal human limits. To shoot scenes as a one-armed character, Wang Yu had his right arm strapped to his back.

In spite of its similar name, it has no relation to The One-Armed Swordsman, the 1967 film that made Wang Yu famous.

It was followed by a 1976 sequel, Master of the Flying Guillotine, with Wang Yu reprising his role and returning as writer and director.
