Junchen (Chinese: 軍臣, Old Chinese (ZS): *kun-gin; r. 161–126 BCE) was the son and successor to Laoshang Chanyu. As chanyu of the Xiongnu Empire, Junchen outlived the Han emperors Wen (r. 180–157 BC), Jing (r. 157–141 BC). He died during the reign of the Emperor Wu of Han (r. 141–87 BC). All three Han emperors confirmed the heqin peace and kinship treaty with the Xiongnu.
