Hats with horns are hats equipped with the horns of various animals, more often bison, or their imitation.

They were distributed as military and ceremonies among the North American Indians in the Great Plains, Plateau and the Great Basin region. Like many other Indians, such hats were considered filled with magical and protective property or power. Honorary bison horns or similar structures made of wood or leather were sometimes supplied with hats in the form of feather crowns.
