The Battle of Yehuling, literally the Battle of Wild Fox Ridge, was a major decisive battle fought between the Mongol Empire and Jurchen-led Jin dynasty during the first stage of the Mongol conquest of the Jin dynasty. The battle was fought between August and October 1211 at Yehuling (野狐嶺; lit. "Wild Fox Ridge"), which is located northwest of present-day Wanquan District, Zhangjiakou, Hebei Province. The battle concluded with a total Mongol victory that allowed them to overrun and conquer the northern part of the Jin. It also hastened the weakening and decline of the Jin dynasty.
