Riot V, formerly known as Riot, is an American heavy metal band formed in New York City in 1975 by guitarist Mark Reale. Reaching peak in popularity in the early 1980s, the band has continued a long-running successful career. Riot's sound initially started out as straightforward heavy metal, but since their 1988 release Thundersteel, their musical style has shifted a little towards power metal.

In 2013, surviving members of the band re-incarnated the band to Riot V, after the death of founding member, guitarist, main songwriter and leader Mark Reale.

The group uses a baby seal face as a logo on its album covers.
