Sun Qifeng (1583–1675; 孙奇逢; Sūn Qíféng or Sun Ch'i-feng in Wade Giles) was an official who served the Ming Dynasty. He was a native of Rongcheng County in Zhili Province. He passed the imperial examination for xiucai when only thirteen years of age, and graduated as juren in 1600; but disgusted with the prospects of the Ming dynasty, clouded by the development of eunuch dominion, he devoted himself to a life of study and retirement. Often invited to take office by Emperors both of the Ming and Qing dynasties, he ever steadfastly declined; though in 1636 he did take part in the successful defence of Roncheng against Li Zicheng. He is one of the most famous masters of Confucian ethics, and his works on the Four Books etc. have been recommended to students by Zhang Zhidong in the 19th century. He also wrote on Ceremonial, and published the lives of eleven famous Confucians. He taught in a college near Suzhou during the last twenty-five years of his life, and in 1828 he was admitted into the Confucian Temple.

孙奇逢（1585年 - 1675年），字启泰，号钟元。直隶保定府容城县（今属河北省）人。明末清初理学大家。学生包括费密、申涵光等。

原籍明直隶保定府容城县（今属河北省），后迁居河南卫辉府辉县。万历庚子举人，与东林党人来往密切。左光斗等东林六君子受阉党魏忠贤迫害，忠贤诬陷光斗等贪污数万两白银，要求追出赃款。孙奇逢与鹿正（主事鹿善继父）、张果中等人一面写信要求曾为帝师的榆关督师孙承宗出面营救，三人又四处募款，代为上缴，但未及营救，六君子皆死，孙奇逢等人被赞为范阳三烈士。

明亡，清廷屡召不仕，人称孙徵君。与李顒、黄宗羲齐名，合称明末清初三大儒。有《读易大旨》五卷、《理学宗传》、《圣学录》等著，晚年讲学于辉县夏峰村，世称夏峰先生。钱锺书认为，「方苞写孙奇逢传，人家看了不满意，认为孙奇逢的为人，有三个特点：一是他的讲学宗旨比较突出，主张身体力行；二是他的义侠之迹，在明末乱世，他能够率领几百家据守险要，保全乡里；三是他的门墙广大，教育了很多人才。」
