Song Zhiwen (c. 660–712), also known by his courtesy name of Yanqing, was a Chinese poet of the early Tang dynasty, although technically his poetic career was largely within the anomalous dynastic interregnum of Wu Zetian. Together with Shen Quanqi, Song Zhiwen is considered to have the "credit for the final perfection" of the "new style" poetry of regulated verse (jintishi) which was one of the most critical poetic developments of the early Tang poets, and much followed as a style which inspired future generations of poets.
He was ordered to commit suicide after Emperor Xuanzong came to the throne, ostensibly because of his unwise involvement in the politics of the imperial succession.
