Kirsten Marie Bråten Berg (born 7 January 1950 in Arendal, Norway) is a Norwegian folk singer, silversmith and government scholar. She is currently living in Valle in the Setesdal area of southern Norway. She trained as a silversmith at the Torleiv H. Bjørgums Vocational College (Oslo Yrkesskole an Torleiv H. Bjørgums) in Setesdal and then set up her own workshop there, in Nomeland.
She began singing traditional Norwegian folk songs in the 1970s and since the late 1970s has given concerts and made recordings, winning Spellemannprisen awards (the Norwegian equivalent of the Grammy award) in 1979 and 1988. She met the bass player Arild Andersen in 1990 and became a member of his group in 1992.
Bråten Berg's interest in the Norwegian folksong tradition has led her to meet and learn from older Norwegian musicians and people or from recordings of their music-making. Alongside figures such fiddler Hallvard Bjørgum, she exemplifies those Norwegian folk musicians trying to carry their tradition into modern times.
In 2005, she was made a Knight First Class of The Royal Norwegian Order of St. Olav in recognition of her work as a performer and ambassador of Norwegian culture.
She has also collaborated with West African musicians on the CD From Senegal to Setesdal.
