A barber is a person whose occupation is mainly to cut, dress, groom, style and shave hair or beards. A barber's place of work is known as a barbershop or the barber's. Barbershops have been noted places of social interaction and public discourse since at least classical antiquity. In some instances, barbershops were also public forums. They were the locations of open debates, voicing public concerns, and engaging citizens in discussions about contemporary issues.

The barber surgeon, one of the most common European medical practitioners of the Middle Ages, was generally charged with caring for soldiers during and after battle. In this era, surgery was seldom conducted by physicians, but instead by barbers, who, possessing razors and dexterity indispensable to their trade, were called upon for numerous tasks ranging from cutting hair to pulling teeth to amputating limbs.
