Sofia Karlsson is a Swedish folk singer.

Svarta ballader is the classically-trained Swedish folk musician Sofia Karlsson's second studio album, released in 2005. On the disc she exclusively interprets poems written by the Swedish proletarian school author Dan Andersson; five of the eleven poems are from his 1917 collection Svarta ballader. The poems are set to music by different composers, including the singers Gunnar Turesson, Gunde Johansson, and Thorstein Bergman; the musician Sven Scholander; a member of Karlsson's band, Sofie Livebrant, and Karlsson herself; while one song was set by Andersson. Karlsson and her band arranged all the songs, with novel instrumentation including cello, trumpet, bass clarinet, piano and percussion.
