Karin Krog (born 15 May 1937) is a Norwegian jazz singer.

Krog began singing jazz as a teenager and attracted attention while performing in jam sessions in Oslo. In 1955, she was hired by the pianist Kjell Karlsen to sing in his sextet.^[1][2] In 1962, she started her first band, and that same year she became a student of the Norwegian-American singer Anne Brown. Krog studied with Brown until 1969. In the 1960s, she performed with the rhythm and blues band Public Enemies, releasing the hit singles "Sunny" and "Watermelon Man".^[1][2][3]

She has worked with Vigleik Storaas, Jacob Young, Terje Rypdal, Arild Andersen, Jan Garbarek, Dexter Gordon, Kenny Drew, Don Ellis, Steve Kuhn, Archie Shepp, Paul Bley, John Surman, Niels-Henning Ørsted Pedersen, Red Mitchell, and Bengt Hallberg.^[1][2][4][5] In 1994, she became the first Norwegian musician to have an album released by Verve Records. The album Jubilee was a compilation of songs from her thirty-year career.^[2]

Krog is the great granddaughter of Anders Heyerdahl (1832–1918), a Norwegian composer, musician, genealogist, folklorist and local historian. She was married (1957–2001) to the jazz journalist Johannes (Johs.) Bergh (1932–2001).^[1][2] Her long-term partner is British jazz multi-instrumentalist John Surman.^[6]
