Jingyu is a county in southern Jilin province, People's Republic of China. It falls under the administration of Baishan City. Until February 1946 it was known as Méngjiāng County, when it was renamed.
The county is named after General Yang Jingyu, who was killed there during World War II. The renaming in 1946 honoured the general, who is a well-known figure in Chinese wartime history.
