Bu Bing or Wai Bing (born Zǐ Shèng ), was the second king of the Shang dynasty, according to the Records of the Grand Historian.

In the Records of the Grand Historian, he was listed by Sima Qian as the second Shang king, succeeding his father Tang, following the earlier death of his elder brother Tai Ding. He was enthroned in the year of Yihai , with Yi Yin as his prime minister and Bo as his capital. He ruled for about 2 years before his death.

Oracle script inscriptions, on bones unearthed at Yinxu, alternatively record that he was the fourth Shang king, the second son of Da Ding, given the posthumous name "Bu Bing" , and succeeded by Da Geng.
