Quiet Riot is an American heavy metal band, whose 1983 & 1984 success contributed to launching the 1980s glam metal scene. They were founded in 1973 by guitarist Randy Rhoads and bassist Kelly Garni, and the original lineup featured lead vocalist Kevin DuBrow, Kelly Garni, and drummer Drew Forsyth.

Some have guessed that the name "Quiet Riot" comes from a phrase in John Barth's 1960s novel Giles Goat-Boy and/or to be a pun on the title of "White Riot" by The Clash. However, in a radio interview given by the band in 1979 and available here, DuBrow said the band's name was born of a conversation with Rick Parfitt of British band Status Quo in which Parfitt said he'd like to name a band "Quite Right". They are ranked at number 100 on VH1's "100 Greatest Artists of Hard Rock."

Quiet Riot also has one of the most famous and iconic heavy metal mascots in history. Their mascot resembles a man (sometimes lead singer Kevin DuBrow) in a metal facial mask and in a straightjacket (somewhat similar to Hannibal Lecter) which has appeared on almost every single Quiet Riot album. This mascot has been considered along-side Megadeth's Vic Rattlehead, Iron Maiden's Eddie the Head and Motörhead's "Snaggletooth" as the all-time most familiar heavy metal symbols.
