Jiang Jing is a fictional character in Water Margin, one of the Four Great Classical Novels of Chinese literature. He ranks 53rd of the 108 Liangshan heroes and 17th of the 72 Earthly Fiends. He is nicknamed "Divine Mathematician".

Jiang Jing is from Tanzhou (潭州; around present-day Changsha, Hunan). He attempted the imperial examination in his younger days but was not a successful candidate. He shifted his focus from academics and literature to military studies instead. He achieves great success after years of effort and becomes an expert in martial arts, mathematics and military strategy. He earns himself the nickname "Divine Mathematician". Later, he joins a bandit gang based on Mount Yellow Gate (黃門山) and becomes one of their leaders, alongside Ou Peng, Tao Zongwang and Ma Lin.

After saving Song Jiang and Dai Zong in Jiangzhou (江州; east of present-day Chongzuo, Guangxi), the outlaws from Liangshan Marsh are making their way back to base when they passed by Mount Yellow Gate along the way. The four bandit chiefs stop the Liangshan outlaws and request to join them. Song Jiang agrees and they return to Liangshan together.

Jiang Jing becomes an accountant in Liangshan after the Grand Assembly of the 108 Stars of Destiny. He is in charge of keeping records of exports and imports of provisions. He follows the heroes on their campaigns against the Liao invaders and rebel forces after they have been granted amnesty by Emperor Huizong and is one of the few lucky survivors after the final campaign against the rebel leader Fang La.
