Raggamuffin music, usually seen as ragga, is a subgenre of dancehall and reggae music. The instrumentals primarily consist of electronic music. Similar to hip hop, sampling often serves a prominent role in raggamuffin music.

Wayne Smith's "Under Mi Sleng Teng", produced by King Jammy in 1985 on a Casio MT-40 synthesizer, is generally recognized as the seminal ragga song. "Sleng Teng" boosted Jammy's popularity immensely, and other producers quickly released their own versions of the riddim, accompanied by dozens of different vocalists.

Ragga is now mainly used as a synonym for dancehall reggae or for describing dancehall with a deejay chatting rather than singjaying or singing on top of the riddim.
