The Battle of Bi (Chinese: 邲之戰; pinyin: Bì zhī Zhàn) was fought during the Spring and Autumn period of Ancient China in 597 BC, between the major states of Chu and Jin.

The Jin–Chu rivalry had last come to a head with the decisive defeat of Chu at the Battle of Chengpu, where Duke Wen of Jin became hegemon among the states; after the death of Duke Wen, Chu attempted to reassert its position with northern campaigns, but the presence of Zhao Dun as premier of Jin rendered them unwilling to risk direct conflict.

[2] Xun Linfu, after hearing of Zheng's switch of allegiance, was in favour of retreating; however, his adjutant Xian Hu, maintaining that it would be cowardly to avoid battle as the hegemonic state, led his own troops across the Yellow River without instructions.

Meanwhile, on the Chu side, King Zhuang was intimidated by the presence of the Jin army; even his commander Sunshu Ao was initially in favour of retreat.

King Zhuang, upon winning the battle, led his generals to water their horses from the Yellow River; a request to pursue and destroy the remnant forces was rebuffed on the grounds that, with the humiliation of Chengpu avenged, there was no need for more slaughter.
