Duke Yi of Lu, personal name Ji Xi, was a ruler of the Lu state, succeeding his father Duke Wu.

Despite being the younger son of Duke Wu, he was made heir apparent over his older brother Kuo by the intervention of King Xuan of Zhou. After nine years of rule, supporters of Kuo and of his son Boyu rose in revolt and murdered Duke Yi; Boyu was then proclaimed to be the Duke of Lu by the rebels.
