A model is a person who poses or displays for purposes of art, fashion, or other products and advertising.

Modeling is distinguished from other types of public performance, such as an acting, dancing or mime artistry, although the boundary is not well defined. Appearing in a movie or a play is generally not considered to be modeling, regardless of the nature of the role. However, models generally have to express emotion in their photographs, and many models have also described themselves as actors. Types of models include glamour, fashion, fitness, bikini, fine-art, and body-part models.
