Chen Sanli (23 October 1853 – 14 September 1937) aka Boyan, Sanyuan Laoren, was a Chinese poet who wrote in the classical style in the early modern era.

Along with Zheng Xiaoxu and Shen Zengzhi, he became one of the leading figures of the Tongguang school, which was related to but not identical with the Song poetry style [Kowallis, pp. 168–208].

After the Empress Dowager suppressed the Hundred Days Reform of 1898, the Chens were forced to leave the government and go into internal exile near Jiujiang.

After the 1911 Xinhai Revolution, Chen Sanli declined to serve in government under the Republic, but he was not a Qing yilao [loyalist] in the classic sense.

Chen Sanli was said to have learned from the Northern Song poet Huang Tingjian, but he did not imitate, he developed this style [Kowallis, p. 194].
