Wei Yingwu (traditional Chinese: 韋應物; simplified Chinese: 韦应物; pinyin: Wéi Yìngwù) (737–792) (also transliterated into English "Wei Yinwu" or "Wei Yin-wu") was a Chinese poet of the Tang Dynasty. Twelve of Wei's poems have been included in the Three Hundred Tang Poems anthology.
According to John C. H. Wu, the turbulence and lack of strong central leadership of China during Wei Yingwu's poetry-writing years was a major influencing factor upon his work. One example of such sociopolitical turmoil is the An Shi Rebellion of 755-763. Wu suggests that images such as the boat moving without a person steering in "At Chuzhou on the Western Stream" is a reference to the ship of state without a person at the helm.
