Bragi Ólafsson (born 11 August 1962 in Reykjavík, Iceland) is an Icelandic musician and a writer.
Internationally he is best known for his work as a bassist in The Sugarcubes, the avant-garde pop band from Iceland that brought fame to Björk, who went on to solo success with her unique brand of diverse musical genres.
The Sugarcubes, who favoured strange, offbeat melodies, came together in 1986, but the Sugarcubes' members had played together in different combinations in various Icelandic groups before.
