'New Yi [River]') is a county-level city under the administration of Xuzhou, Jiangsu province, China.

It borders the prefecture-level cities of Linyi (Shandong) to the north, Lianyungang to the northeast, and Suqian to the east and south.

The archaeological site of Huating, located in the southwestern part, was inhabited as long as 5,000 years ago.

During the Zhou dynasty, its southern territory was dominated by a minor state: Zhongwu, which was variously annexed to Wu, Yue and Chu.

It named after the seat, Xin'an (新安) town, but was renamed Xinyi, a river flowing through its area, in 1952, because of its namesake in Henan.
