Kim Kashkashian, internationally recognized as a unique voice on the viola, was born of Armenian parents in Michigan. She studied the viola with Karen Tuttle and legendary violist Walter Trampler at the Peabody Conservatory of Music in Baltimore. Since fall 2000 she has taught viola and chamber music at New England Conservatory.

Following Grammy Award nominations for several previous recordings, Kashkashian received a 2012 Grammy Award in the "Best Classical Instrumental Solo" category for Kurtág and Ligeti: Music for Viola, on the ECM Records label. Kashkashian's recording, with Robert Levin, of the Brahms Sonatas won the Edison Prize in 1999. Her June 2000 recording of concertos by Bartók, Eötvös and Kurtág won the 2001 Cannes Classical Award for a premiere recording by soloist with orchestra.

In 2016, Kashkashian was elected a Fellow of the American Academy of Arts and Sciences.

Kashkashian has worked tirelessly to broaden the range of technique, advocacy, and repertoire for the viola. A staunch proponent of contemporary music, she has developed creative relationships with György Kurtág, Krzysztof Penderecki, Alfred Schnittke, Giya Kancheli, and Arvo Pärt, and commissioned works from Peter Eötvös, Ken Ueno, Thomas Larcher, Lera Auerbach, and Tigran Mansurian.

Marlboro Music and the Viennese school represented by her mentor, Felix Galimir, were major influences in developing her love of chamber music. Kim Kashkashian is a regular participant at the Verbier, Salzburg, Lockenhaus, Marlboro, and Ravinia festivals.

She has long-standing duo partnerships with pianist Robert Levin and percussionist Robyn Schulkowsky, and played in a unique string quartet with Gidon Kremer, Daniel Phillips, and Yo-Yo Ma.

Kashkashian's musicianship has been well represented on recordings through her association with the prestigious ECM label in a fruitful collaboration that has been continuous since 1985.
