Marquis Xiao of Jin, personal name Ji Ping, was a monarch of the Jin state.
In 739 BC, Jin official Panfu (潘父) murdered Marquis Zhao (Marquis Xiao's father) and attempted to place Huan Shu of Quwo on the Jin throne. Huan Shu of Quwo was met with resistance and receded back to Quwo. Then, the Jin people supported Marquis Xiao to take over as the next Jin marquis. After Marquis Xiao ascended the throne, he killed Panfu in revenge for his father.
In 724 BC, the son of Uncle Huan of Quwo, Count Zhuang of Quwo, murdered Marquis Xiao while in the capital of Jin, Yi (翼). Then, Jin troops attacked Count Zhuang of Quwo, resulting in the latter's retreat to Quwo. The Jin people then supported Marquis Xiao's younger brother, Ji Xi, as the next Jin ruler.
