Geng Jingzhong (Chinese: 耿精忠; pinyin: Gěng Jīngzhōng; Wade–Giles: Keng Ching-chung; died 1682) was a powerful military commander of the early Qing dynasty.

[2] Firmly entrenched as a quasi independent ruler in Fujian, in 1674 Geng Jingzhong rebelled against Qing rule along with the other two of the Three Feudatories Wu Sangui and Shang Zhixin, who were also governing enormous principalities in south China.

[3] The Qing then used Geng's troops to fight the other feudatories until the civil war ended.

Soon after the Qing final victory in 1681, the Kangxi Emperor had Geng executed by slow slicing for treason.

Geng Jingzhong's brother Geng Juzhong was in Beijing with the Qing court with the Kangxi Emperor during the rebellion and was not punished by the Kangxi Emperor for his brother's revolt.
