Liu Yong (1719-1804) was a politician, calligrapher and painter of the Qing Dynasty from Zhucheng (now Gaomi, Shandong).

As a metropolitan graduate (Jinshi) during Emperor Qianlong's reign, he was appointed as Minister of Ritual Propriety and Minister of War. He was not only a knowledgeable scholar, but also an eloquent politician. Being proficient with Chinese classics and histories, he was especially good at the textology on the ancient Chinese.

As an incorruptible official, he was devoted to working for the public interests and therefore stood high in public love and esteem. Besides, well-received in the Qing Dynasty, his writings and calligraphy works were mainly done in running script. He ranked the first among the four greatest calligraphers of the Qing Dynasty.
