Mouth Music is a Scottish-inspired musical project founded in 1988, whose combination of traditional Gaelic songs and music with contemporary instrumental and technological settings led them to international fame in the early 1990s.

Mouth Music has featured a variety of musicians over the years, with songwriter, multi-instrumentalist and producer Martin Swan as the only consistent member (and de facto leader). Other musicians who have passed through the project include singers Talitha MacKenzie, Jackie Joyce (aka Helicopter Girl), Martin Furey, Jaq Ferry, Màiri MacInnes, Ishbel MacAskill and Michaela Rowan, plus fiddler Alison Crawford, Capercaillie/Shooglenifty drummer James Mackintosh, and pipe/flute/fiddle player Martyn Bennett.

Swan has commented "I've never seen Mouth Music as a group. It's always been me with different people joining to play live."

The name "Mouth Music" is an English translation of the Gaelic term puirt a beul – the vocalisation of instrumental music.
