Zhou Yin (simplified: 周胤, traditional: 周胤, pinyin: Zhōu Yìn) was a son of Zhou Yu. He was enfeoffed as a marquis in recognition of his father’s merit. He later fell into disfavour with Sun Quan and was stripped of his marquisate and sent to Luling. In 238, Bu Zhi and Zhuge Jin memorialised asking Sun Quan to show leniency to Zhou Yin for Zhou Yu’s sake; Sun Quan agreed, but before the order reached him Zhou Yin had already died.
