Isabelle Faust (born 19 March 1972) is a German violinist who has worked internationally as a soloist and chamber musician.

Her father, then a 31 year old secondary school teacher, decided to learn the violin.

The early start was, for both the children, the basis for musical careers; Boris Faust has become a viola professional.

After winning the Paganini Competition, and keen to broaden her experience, she moved in 1996 to Paris where she lived for the next nine years.

In addition to the recordings listed under "Awards and Prizes," she has recorded works of Ludwig van Beethoven, Antonín Dvořák, Robert Schumann, Franz Schubert, Johannes Brahms (including the Violin Concerto), Alban Berg, Bohuslav Martinů, André Jolivet and others.

She is a proponent of new music and has given world premieres of works by, among others, Olivier Messiaen, Werner Egk, Péter Eötvös, and Jörg Widmann.
