The river has its sources on the Central Russian Uplands, and flows through Kursk and Belgorod Oblasts in Russia, and through the eastern part of Kharkiv Oblast in Ukraine, where it joins the Seversky Donets river. An artificial lake, the Oskol Reservoir (Oskil Reservoir, Оскільське водосховище), was created in 1958 to help with flood protection and as a source of electricity.

There are several towns along the Oskol: Stary Oskol, Novy Oskol and Valuyki in Russia, and Kupiansk in Ukraine.
