Li Yan (died October 234), courtesy name Zhengfang, also known as Li Ping, was a military general of the state of Shu Han during the Three Kingdoms period of China. He climbed to the zenith of his career when he was asked by the Shu emperor Liu Bei to be the military paramountcy and co-regent alongside Zhuge Liang for his son and successor, Liu Shan.
