Sun Yirang (Chinese: 孫詒讓; pinyin: Sūn Yíràng; 1848–1908) was a late Qing dynasty Chinese philologist. A native of Wenzhou, Zhejiang province, he retired from official employment early in his life to devote himself to scholarship. His most important works are Mozi Jiangu (墨子間詁), a corrected, definitive edition of Mozi, and Zhouli Zhengyi (周禮正義), an important commentary on the Rites of Zhou. He also contributed to the studies of the bronzeware script and oracle script. His work Qiwen Juli (契文舉例), published posthumously by Luo Zhenyu, was the first work of decipherment of the oracle bone script.
