Levski (Bulgarian: Левски) is a town in central northern Bulgaria, an administrative center of the homonymous Levski Municipality in the very southeast of Pleven Province. It is located in the valley of the Osam River and was called Karağaç (Turkish for "black elm") during the Ottoman rule of Bulgaria and until 1897, when it was renamed after the Bulgarian national hero Vasil Levski. The then-village was proclaimed a town in 1945, reportedly the first to become one after World War II in Bulgaria.
