Xi Zezong (June 6, 1927, Yuanqu, Shanxi – December 27, 2008, Beijing) was a Chinese astronomer, historian, and translator. He was a member of the Chinese Academy of Sciences, and an awardee of the Astronomy Prize.

He identified a possible reference to one of the Galilean moons of Jupiter in the fragmentary ancient works of the 4th-century BC Chinese astronomer Gan De, who may have made observation of either Ganymede or Callisto in summer 365 BC.
