A hackamore is a type of animal headgear which does not have a bit. Instead, it has a special type of noseband that works on pressure points on the face, nose, and chin. It is most commonly associated with certain styles of riding horses. The hackamore is sometimes known as a bitless bridle. It's a piece of tack that has a headstall and reins like a traditional bridle but, rather than a bit, has a specialized noseband for steering and control.
