Michael Jarrell (born 8 October 1958) is a Swiss composer and academic teacher, whose operas, such as Cassandre, have been performed internationally.

From 1986 to 1988, he was resident at the Cité des Arts in Paris, taking part in the computer music course at IRCAM.

His next residency was at the Villa Medici (1988–89), home of the French Academy in Rome, followed by membership of the Istituto Svizzero di Roma in 1989–90, after which he became composer-in-residence at the Orchestre de Lyon (October 1991–June 1993).

In 1993, Jarrell was appointed professor of composition at the University of Music and Performing Arts, Vienna.

His "spoken opera" Cassandre, which is based on Christa Wolf's novel Cassandra, was premiered in Paris in 1994 and performed at the Ojai Festival, CA, in June 2008.
