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 (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.
