A handkerchief /ˈhæŋkərɪf/, also called a handkercher or hanky, is a form of a kerchief, usually made of thin fabric that can be carried in the pocket or purse. It was invented for personal hygiene purposes such as wiping one's hands or face, or blowing one's nose.

A handkerchief is also sometimes used as a purely decorative accessory in a suit pocket.
