Wugunai (1021–1074) was a chieftain of the Wanyan tribe, the most dominant among the Jurchen tribes which later founded the Jin dynasty (1115–1234). He was the eldest son of Shilu. Like his father, Wugunai was appointed chieftain of the Wanyan tribe by the Khitan-led Liao dynasty, which ruled northern China between the 10th and 11th centuries. Historical sources describe Wugunai as a brave warrior, great eater and hard drinker, and a lover of women.
Wugunai was posthumously honoured with the temple name Jingzu (景祖) by his descendant, Emperor Xizong.
