Khar Lake (Mongolian: Хар нуур, lit. "black lake"), also known as Ha-la Hu, Hara Nuur, Har Nuur, Khara Nur, Khar Nuur, and Ozero Kara-Nor, is located in the Khovd aimag (province) in western Mongolia's Great Lakes Depression. It is part of a group of lakes that were once part of a larger prehistoric lake that disappeared 5,000 years ago as the region became drier.

It should be distinguished from the similarly named Khar Lake (Zavkhan), further east in Mongolia
