Yang Bojun (Chinese: 杨伯峻; Wade–Giles: Yang Po-chün; 1 September 1909 − 1992) was a Chinese philologist best known for his Chunqiu Zuozhuan Zhu (春秋左传注), an annotated commentary of the ancient Chinese historical text and Confucian classic Zuo Zhuan. The work took him more than twenty years to finish. His commentaries of the Analects of Confucius and the Mencius are also highly influential.
