The Bori River is a tributary of the Bhima River, the main tributary of the Krishna River, in Maharashtra and Karnataka, India. It rises in the Balaghat Range near the hills of Dharur and flows southwards towards Akkalkot. Important places on or near its course include the town of Tuljapur, and the medieval fort of Naldurg.[1] The Kurnur Dam at the confluence of Bori and the Harna river provides water for the area around Akkalkot.[2] It meets the Bhima from the left near Afzalpur on the Karnataka side of Maharashtra-Karnataka border.
