The Tomb of Marquis Yi of Zeng (Chinese: Zeng Hou Yi) is an important archaeological site in Suizhou; Hubei; China; dated sometime after 433 BCE. The tomb contained the remains of Marquis Yi of Zeng; and is one of a handful of ancient Chinese royal tombs to have been discovered intact and then excavated using modern archaeological methods.

Zeng was a minor state subordinate to its powerful neighbor; Chu. The tomb was made around 433 BCE; near the start of the Warring States period. The tomb comes from the end of the thousand-year-long period of the burial of large sets of Chinese ritual bronzes in elite tombs; and is also unusual in containing large numbers of musical instruments; including the great set of bells for which it is most famous.
