The One-Armed Swordsman is a 1967 Hong Kong wuxia film produced by the Shaw Brothers Studio. Directed by Chang Cheh, it was the first of the new style of wuxia films emphasizing male anti-heroes, violent swordplay and heavy bloodletting. It was the first Hong Kong film to make HK$1 million at the local box office, propelling its star Jimmy Wang to super stardom.

This film eventually became the first in the One-Armed Swordsman trilogy. A sequel was released in 1969 called Return of the One-Armed Swordsman, followed by The New One-Armed Swordsman in 1971, all directed by Chang Cheh. It has since achieved classic status in Hong Kong cinema. In the Hong Kong Film Award's 2005 poll, The One-Armed Swordsman was voted as the 15th best Chinese-language film.
