Zu Yue (祖約) (after 266[1] - March or April 330[2]), courtesy name Shishao, was a Chinese military general and warlord of the Jin dynasty.
He was the younger brother of the famed Jin general Zu Ti who marched north to reclaim lost lands from the barbarians.
In his youth, Zu Yue received the title of "Xiaolian (孝廉; Filial and Incorrupt)" and worked as the Magistrate of Chenggao County.
The Minister of Justice, Liu Wei (劉隗), wanted to execute him for his negligence but Sima Rui prevented him from doing so.
Zu Yue found his new position difficult to hold, as his lack of ability to impose discipline and poor relations with his brother's generals made him very unpopular among his men.
Zu Yue failed to hold out and lost Xiangcheng, Chengfu (城父, in present-day Bozhou, Anhui) and Chenliu as a result.
[6] In 324, Zu Yue joined the loyalist side during Wang Dun's second insurrection against Jin after he was summoned to the capital by Emperor Ming.
Zu Yue drove out Wang's Administrator of Huainan Ren Tai (任台) at Shouyang (壽陽, in present-day Lu'an, Anhui).
Su Jun knew of Zu Yue's grudge with Yu Liang and the government, so he was offered to join forces.
[11] The Jin general, Wen Jiao, issued a call to arms against Su Jun and Zu Yue.
[13] With his deteriorating relationship with his staff and the mounting defeats, Zu Yue's generals plotted with Later Zhao to kill him.
The situation for Zu Yue continued to worsen as the loyalist Zhao Yin (趙胤) attacked his base the next year.
