Yang Xi (died 261), courtesy name Wenran, was an official of the state of Shu Han during the Three Kingdoms period of China. He is best known for writing the Ji Han Fuchen Zan (季漢輔臣贊; pub. 241), a collection of praises of notable persons who served in the Shu Han state. Chen Shou, the third-century historian who wrote the Records of the Three Kingdoms (Sanguozhi), extensively quoted and annotated Yang Xi's collection.
