Koshares are Pueblo clowns (sometimes called sacred clowns) are jesters or tricksters in the Kachina religion (practiced by the Pueblo natives of the southwestern United States). It is a generic term, as there are a number of these figures in the ritual practice of the Pueblo people. Each has a unique role; belonging to separate Kivas (secret societies or confraternities) and each has a name that differs from one mesa or pueblo to another. The clowns perform monthly rituals, summer (for rain), November - for the gods, for curing society, black magic. In order for a clown to perform meaningful social commentary via humor, the clown's identity must usually be concealed. The sacred clowns of the Pueblo people, however, do not employ masks but rely on body paint and head dresses.

These individuals present themselves with black and white horizontal stripes painted on their bodies and faces, paint black circles around the mouth and eyes, and part their hair in the center and bind it in two bunches which stand upright on each side of the head and are trimmed with corn husks.
