Carolyn Breuer (born 4 July 1969 in Munich) is a German jazz saxophonist (alto and soprano).
She is the daughter of the popular jazz musician Hermann Breuer. When she was 19 years old, she studied as a member of the Bundesjazzorchester at the Konservatorium in Hilversum under Ferdinand Povel. After her examination, she moved to New York City for a long time where she took private lessons with George Coleman and Branford Marsalis.
Breuer worked together with Coleman, Fee Claassen and Ingrid Jensen and began her own label, NotNowMom!-Records. The CD, Serenade, won the "Heidelberger Künstlerpreis" (Heidelberg's prize for artists) in Amsterdam. She is the first jazz musician to receive this award, previously only given to classical musicians. She has undertaken many international tours and shows such as WDR's Big Band, the Berlin Jazz Festival, and the North Sea Jazz Festival). Her album, Fate Smiles On Those Who Stay Cool, became so popular in the Netherlands that politician Klaas De Vries began a speech in parliament with exactly those words.
