Empress Zhang (died July or August 237), personal name unknown, formally known as Empress Jing'ai (lit. "Respectful and Lamentable Empress"), was an empress of the state of Shu Han in the Three Kingdoms period. She was a daughter of the Shu general Zhang Fei. She married Liu Shan in 221 and became the crown princess of Shu. In 223 when Liu Bei died, Liu Shan ascended the throne of Shu, and Zhang became the empress. She died in 237 and was buried in Nanling (南陵). She was succeeded by her younger sister. In the novel Romance of the Three Kingdoms she doesn't marry Liu Shan until after he becomes Emperor, with Zhuge Liang recommending her due to her prudence.
