King Xi of Zhou (died 677 BC) (), personal name Ji Huqi, was a king of the Chinese Zhou dynasty.
He was the successor to his father King Zhuang, and was in turn succeeded by his son, King Hui.
By the time of King Xi's reign, China proper had dissolved into a multitude of Warring States, only nominally subject to the Eastern Zhou king, who was no longer even the most powerful figure (that was Duke Huan of the Qi state).
