Huyandi (Chinese: 壺衍鞮) was the son and successor of Hulugu Chanyu. He ruled as the Chanyu of the Xiongnu Empire from 85 to 68 BC.^[1]

Huyandi was not first in the line of succession and only became chanyu, due to a plot by his mother Zhuanqu Yanzhi and the Han defector Wei Lü. He came to power in 85 BC.^[2]

In 71 BC, Chang Hui and two other generals led a force of 100,000 to aid the Wusun against the Xiongnu. The majority of the forces failed to find any Xiongnu, but Chang Hui successfully aided the Wusun in defeating a Xiongnu invasion. However, the Xiongnu came back in winter and took many captives. On the way back across the Altai Mountains, the Xiongnu suffered heavy casualties from a sudden blizzard, devastating their army. The next year the Xiongnu were attacked on all sides by Wusun, Wuhuan, and the Han. One-third of all Xiongnu died.^[3]

Huyandi died in 68 BC and was succeeded by his brother, Xulüquanqu.^[1]
