Killbuck, also known as Bemineo, was a Delaware war chief, medicine man, and leader. He led attacks on frontier settlements in what is now eastern West Virginia during the French and Indian War.

In 1756, Killbuck and his warriors killed several militiamen at the Battle of the Trough. In 1758, he attacked Fort Seybert (pictured), where many settlers were killed or taken captive. He likely was involved in the destruction of nearby Fort Upper Tract the previous day.

He died in 1779 in what is now Coshocton, Ohio.
