Wai Ren ({{zh|外壬}}) or Bu Ren ({{zh|卜壬}}), personal name Zi Fa, was a Shang dynasty King of China.

In the Records of the Grand Historian he was listed by Sima Qian as the eleventh Shang king, succeeding his brother Zhong Ding ({{lang|zh|仲丁}}). He was enthroned in the year of Gengxu ({{zh|links=no|c=庚戌}}) with Ao ({{lang|zh|隞}}) as his capital. During his reign there was a rebellion from Shang's vassals of Pei ({{lang|zh|邳}}) and Xian ({{lang|zh|侁}}) peoples. He ruled for 15 years (although the Bamboo Annals claim 10 years) before his death. He was given the posthumous name Wai Ren and was succeeded by his son He Dan Jia ({{lang|zh|河亶甲}}).{{cite book |last=Bai |first=Shouyi |title=An Outline History of China |year=2002 |publisher=Foreign Language Press |location=Beijing |isbn=7-119-02347-0}}{{cite web |url =http://chinaknowledge.de/History/Myth/shang-rulers.html |title = The Shang Dynasty Rulers |access-date = August 7, 2007 |publisher = China Knowledge }}{{cite web|url=http://www.indiana.edu/~g380/Kings.pdf |title=Shang Kingship And Shang Kinship |access-date=August 7, 2007 |publisher=Indiana University |archive-url=https://web.archive.org/web/20080409215121/http://www.indiana.edu/~g380/Kings.pdf |archive-date=April 9, 2008 |url-status=dead }}
