A VJ is a performance artist who creates moving visual art (namely video) on large displays or screens, often at events such as concerts, nightclubs and music festivals, and usually in conjunction with other performance art. This results in a live, multimedia performance that can include music, actors or dancers as well as live and pre-recorded video.

The term VJ originates from a parallel with the term Disc Jockey or DJs, although most VJs nowadays have more in common with musicians than with DJs.
