Susanne Alt (born 1978) is a German jazz saxophone player and composer based in Amsterdam, Netherlands.

Between 1993 and 1995, while still in high-school, she started taking lessons in classical saxophone at the Meistersingerkonservatorium Nuremberg, and was a full-time student there during the 1995–96 academic year.

[2] Postgraduate studies brought her back to Germany, where she enrolled in the Berlin University of the Arts in 2000.

She formed her own ensemble, the "Susanne Alt Quartet" in 2003, and in the following year released her debut album, Nocturne at Bimhuis, Amsterdam.

[5][1] The album received great reviews from various (inter)national sources and is considered her most ambitious work to date.
