A horse bridle is a piece of equipment used to control a horse while riding.

It is composed of a headstall, which is a leather or nylon strap that goes around the horse's head, and a bit, which is a metal mouthpiece that fits inside the horse's mouth. The reins, which are attached to the bit, are used by the rider to communicate with the horse and guide it in the desired direction.

The bridle may also include other components, such as a noseband, which helps to keep the horse's mouth closed and prevent it from opening its mouth too wide.

There are various types of bridles available, each with different styles and functions, depending on the riding discipline and the rider's preferences.
