Shang Zhixin (Chinese: 尚之信; 1636 – 1680) was a warlord of the early Qing Dynasty, known for his role in the Revolt of the Three Feudatories.
In 1673, Shang Kexi, on account of old age, requested the Kangxi Emperor to allow him to retire back in his adopted homeland Liaodong.
Not long afterwards, the Qing court, as part of its policy of centralization, decided to abolish Pingnan Feudatory under the pretext that Shang Zhixin was "difficult to control".
Having gained the military command of Pingnan Feudatory, Shang Zhixin promptly joined Wu Sangui's forces.
The Qing court ordered him to lead troops against Wu Sangui, but Shang Zhixin only made token efforts, hoping to preserve his own forces.
