Helian Chang (died 434), courtesy name Huan'guo, nickname, is an emperor of the state Xia.

He is the successor and a son of the founding emperor Helian Bobo (Emperor Wulie).

After his father's death in 425, he tries to expand Xia further, but soon his state begins to collapse in light of pressure from rival Northern Wei.

In 427, his capital Tongwan (in modern Yulin, Shaanxi) falls to Northern Wei forces, and in 428 he himself is captured.

Emperor Taiwu of Northern Wei does not kill him but instead treats him as an honored companion, marrying a sister to him and creating him high titles—initially the Duke of Kuaiji and later the Prince of Qin—but in 434 (after his brother and successor Helian Ding had been captured and executed, ending Xia), he tries to escape and is killed.
