The Battle of Jieting was fought between the states of Cao Wei and Shu Han in 228 during the Three Kingdoms period of Chinese history. The battle was part of the first Northern Expedition led by Shu's chancellor Zhuge Liang to attack Wei. The battle concluded with a decisive victory for Wei.

Zhuge Liang first sent generals Zhao Yun and Deng Zhi to attack Wei, while he personally led a force towards Mount Qi. Cao Rui, the emperor of Wei, moved to Chang'an and sent Zhang He to attack Zhuge Liang while Cao Zhen would oppose Zhao Yun. Zhuge Liang chose generals Ma Su and Wang Ping to intercept Zhang He.

Jieting was a crucial region for the securing of supplies, and Zhuge Liang sent Ma Su and Wang Ping to guard the region. Ma Su went accompanied by Wang Ping but did not listen to his sound military advice. Relying purely on books of military tactics, Ma Su chose to "take the high ground" and set his base on the mountains instead of in a city, ignoring Wang Ping's advice to make camp in a valley well supplied with water. Wang Ping, however, managed to persuade Ma Su to give him command of a portion of the troops, and later Wang set up his base camp near Ma's camp, in order to offer assistance when Ma was in danger. Due to this tactical mistake, the Wei army led by Zhang He encircled the hill and cut off the water supply to the Shu troops and attacked; later, Wei forces set fire to the hill. Wang Ping led his troops in an attempt to help Ma Su but the Shu army suffered a great defeat in which both the army and the fort were lost. Though he survived the battle, Ma Su feared punishment and attempted to flee. However, he was soon captured by Shu forces.

Ma Su was sentenced to death by Zhuge Liang, along with his deputy commanders Zhang Xiu (張休) and Li Sheng (李盛), but Ma eventually died of illness in prison before the execution could be carried out, while the other two were executed.
