A shaving brush or shave brush is a small brush with a handle parallel to the bristles used to make lather from shaving soap or shaving cream and apply it to the face when shaving.

Traditionally shaving brushes have usually been made from badger hair. These days there are a wider variety of bristles to choose from, both natural and synthetic. Most shaving brushes are made from the hair of boars, horses and badgers, or from synthetic fibres.
