Tang Jingsong was a Chinese general and statesman. He commanded the Yunnan Army in the Sino-French War, and made an important contribution to Qing dynasty China's military effort in Tonkin by persuading the Black Flag leader Liu Yongfu to serve under Chinese command. His intelligent, though ultimately unsuccessful, direction of the Siege of Tuyên Quang was widely praised. He later became governor of the Chinese province of Taiwan. Following China's cession of Taiwan to Japan at the end of the First Sino-Japanese War (1894–1895) he became president of the short-lived Republic of Formosa.

The Sino-French War, also known as the Tonkin War, was a limited conflict fought from August 1884 to April 1885. There was no declaration of war.
