Dance (from Old French dancier, perhaps from Frankish) generally refers to human movement either used as a form of expression or presented in a social, spiritual or performance setting.

Dance is also used to describe methods of non-verbal communication (see body language) between humans or animals (bee dance, mating dance), motion in inanimate objects (the leaves danced in the wind), and certain musical forms or genres.

Choreography is the art of making dances, and the person who does this is called a choreographer.

Definitions of what constitutes dance are dependent on social, cultural, aesthetic artistic and moral constraints and range from functional movement (such as Folk dance) to codified, virtuoso techniques such as ballet. In sports, gymnastics, figure skating and synchronized swimming are dance disciplines while Martial arts 'kata' are often compared to dances.
