A browband is one of the parts of a horse's bridle. The crownpiece, headstall (US) or headpiece (UK) goes over the horse's head just behind the animal's ears, at the poll. It is the main strap that holds the remaining parts of the bridle in place.

The crownpiece runs through the browband. The browband runs from just under one ear of the horse, across the forehead, to just under the other ear. It prevents the bridle from sliding behind the poll onto the upper neck, and holds multiple headstalls together when a cavesson or second bit is added, and holds the throatlatch in place on designs where it is a separate strap. In certain sports, such as dressage and Saddle seat, decorative browbands are sometimes fashionable
