Zhong Ding (Chinese: 仲丁, born Zi Zhuang 子庄), was a Shang Dynasty King of China.
In the Records of the Grand Historian he was listed by Sima Qian as the tenth Shang king, succeeding his father Tai Wu (太戊). He was enthroned in the year of Xinchou (Chinese: 辛丑) with Bo (亳) as his capital. In the first year of his reign he moved his capital to Ao (隞). In the sixth year of his reign he attacked the Blue Barbarians (蓝夷). He ruled for 11 years (other sources say 9 years) before his death. He was given the posthumous name Zhong Ding and was succeeded by his brother Wai Ren (外壬).
Oracle script inscriptions on bones unearthed at Yinxu alternatively record that he was the ninth Shang king succeeding his uncle Yong Ji (卜丙), given the posthumous name Sanzu Ding (三祖丁) and succeeded by his brother Bu Ren.
