Cao Ziqin (simplified: 曹子勤, traditional: 曹子勤, pinyin: Cáo Zǐqín) was a son of Cao Cao and Consort Sun (孫姬), and a brother of Cao Biao and Cao Zishang. He died early without producing heirs. In 231, Cao Rui posthumously honoured him as Duke Shang of Gang (剛殤公). Few other details are recorded in the sources.
