A music supervisor is an individual who combines music and visual media. In the musical theatre industry, a music supervisor is often responsible for managing a team of music directors working on any number of musical productions.

The Music Supervisor position is difficult to generalize and highly versatile, depending upon the industry and project the role is involved in. Typically, a music supervisor handles the process of choosing, negotiating, and incorporating pieces of music into visual media (such as a television show or movie), acting as a liaison between the creative and business ends of this process. This position is most active within media based industries, including live events, television, film, advertising, theatre, and video gaming. Music supervisors may work within production companies, film studios, networks, music supervision companies, or do freelance work .

Originally, music was used in silent films to hide mechanical noises within a theatre, like the projector. Often a musician would be present to play improvised or pre-selected pieces along with the visual images on screen . This led to the establishment of the soundtrack, and an emphasis on accompanying silent visual media with music. The demand for music supervisors in the production process solidified in the 1980s, and has continued to grow with the popularity of media soundtracks. Taking advantage of this musical component has become an increasingly feasible marketing strategy for these media outlets, placing a growing responsibility on the music supervisor.
