A model (from Middle French modelle),[1] is a person in a role either to promote, display, or advertise commercial products (notably fashion clothing) or to serve as a visual aide for people who are creating works of art.

Modelling ("modeling" in American English) is considered to be different from other types of public performance, such as an acting, dancing or being a mime artist. The boundary between modelling and performing is, however, not well defined, although such activities as appearing in a movie or a play are almost never labelled as modelling.

Frequently take modelling contracts in addition to their regular work.
