Digunai (24 February 1122 – 15 December 1161), also known by his sinicised name Wanyan Liang and his formal title Prince of Hailing (海陵王, Hǎilíng Wáng), was the fourth emperor of the Jurchen-led Jin dynasty of China. He was the second son of Wanyan Zonggan, the eldest son of the dynastic founder Wanyan Aguda (Emperor Taizu). He came to power in 1150 after overthrowing and murdering his predecessor, Emperor Xizong, in a coup d'état. During his reign, he moved the Jin capital from Shangjing (present-day Acheng District, Harbin, Heilongjiang Province) to Yanjing (present-day Beijing), and introduced a policy of sinicisation. In 1161, after the Jin dynasty lost the Battle of Caishi against the Southern Song dynasty, Digunai's subordinates rebelled against him and assassinated him. After his death, even though he ruled as an emperor during his lifetime, he was posthumously demoted to the status of a prince – "Prince Yang of Hailing" (海陵煬王) – in 1162 by his successor, Emperor Shizong. However, in 1181, Emperor Shizong further posthumously demoted him to the status of a commoner, hence he is also known as the "Commoner of Hailing" (海陵庶人).
