Red Cliff or Chibi is a 2008–2009 internationally co-produced epic war film, based on the Battle of Red Cliffs and the events at the end of the Han dynasty and immediately prior to the Three Kingdoms period in Imperial China. The film was directed by John Woo, and stars Tony Leung Chiu-wai, Takeshi Kaneshiro, Zhang Fengyi, Chang Chen, Zhao Wei, Hu Jun, and Lin Chi-ling. It was Woo's first major film since 2003's Paycheck and his first Chinese-language feature since 1992's Hard Boiled, also starring Leung.

The Battle of Red Cliffs, also known as the Battle of Chibi, was a decisive naval battle in China that took place during the winter of AD 208–209. It was fought on the Yangtze River between the forces of warlords controlling different parts of the country during the end of the Han dynasty. The allied forces of Sun Quan, Liu Bei, and Liu Qi based south of the Yangtze defeated the numerically superior forces of the northern warlord Cao Cao. In so doing, Liu Bei and Sun Quan prevented Cao Cao from conquering any lands south of the Yangtze, frustrating Cao Cao's efforts to reunify the territories formerly held by the Eastern Han dynasty.
