Yingchuan Commandery (Chinese: 潁川郡) was a Chinese commandery from the Warring States period to Tang dynasty, located in modern central Henan province.
After the establishment of Hàn dynasty, it originally became Xin, King of Hán's fief.
In 2 AD, it administered 20 counties: Yangdi, Kunyang (昆陽), Yingyang (潁陽), Dingling (定陵), Changshe (長社), Xinji (新汲), Xiangcheng (襄城), Yan (郾), Jia (郟), Wuyang (舞陽), Yingyin (潁陰), Chonggao (崇高), Xu (許), Yanling (傿陵), Linying (臨潁), Fucheng (父城), Cheng'an (成安), Zhouchengxiu (周承休), Yangcheng (陽城), and Guanshi (綸氏).
In Jin dynasty, Xiangcheng Commandery was formed from the southern part of Yingchuan.
They were administered by Ying Prefecture (潁州, established in 535), later renamed Zheng (鄭州), and in Northern Zhou, again to Xu (許州).
