The Battle of Xiaoting（猇亭之戰）, also known as the Battle of Yiling and the Battle of Yiling and Xiaoting, was fought between the state of Shu and the state of Wu, between the years 221 and 222 in the early Three Kingdoms period of China. The battle is significant because Wu was able to turn the situation from a series of initial losses into a defensive stalemate, before proceeding to win a decisive victory over Shu. The Wu victory halted the Shu invasion and preceded the death of Liu Bei, Shu's founding emperor.
