Rui (Chinese: 芮; Wade–Giles: Jui) was a Chinese vassal state during the Zhou dynasty (1046–256 BCE).
In 703 BC, the rulers of the five states of Western Guo, Rui, Xun (荀國) and Jia (賈國), and Liang, suppressed Duke Wu of Quwo using armed force.
In 641 BC, the State of Qin easily conquered Rui along with the State of Liang.
