Music video or song video (English: Music video, Song video, MV) is a video or short film that matches the entire music or song. Modern music videos are mainly used to promote music records. Even though the origin of music videos can be traced back a long time ago, it was not until the establishment of the American Music Television (MTV) in the 1980s that music videos began to become what they are today and become popular. Music videos can include all film creations. Forms include animation, live action films, documentaries, etc.

The correct abbreviation of "music video" in English is "MV". In Taiwan and other regions, in the early years, the word "MTV" was mistakenly used to refer to music videos. It is generally believed that it should be influenced by the MTV channel influence, but in recent years it has begun to be renamed MV.
