Yao Chang (331–394), courtesy name Jingmao, formally Emperor Wuzhao of (Later) Qin, is the founding emperor of the Chinese/Qiang state Later Qin.

His father Yao Yizhong had been a powerful general and Qiang chieftain under the Later Zhao emperor Shi Hu,.

After Later Zhao's collapse following Shi Hu's death, Yao Chang's older brother Yao Xiang tries to start an independent state but is defeated and killed by Former Qin forces.

Yao Chang becomes a Former Qin general, but after an incident in 384 after the Former Qin emperor Fu Jiān's defeat at the Battle of Fei River, Yao Chang fears that Fu Jiān will kill him and therefore rebels.

He subsequently captures and killsFu Jiān, who had saved his life when Yao Xiang was defeated, causing many historians to view him as a traitor and murderer.
