Midori Goto (五嶋 みどり, Gotō Midori, born October 25, 1971) who performs under the mononym Midori, is a Japanese-born American violinist. She made her debut with the New York Philharmonic at age 11 as a surprise guest soloist at the New Year's Eve Gala in 1982. In 1986 her performance at the Tanglewood Music Festival with Leonard Bernstein conducting his own composition made the front-page headlines in The New York Times. Midori became a celebrated child prodigy, and one of the world's preeminent violinists as an adult.

Midori gave her first public performance at the age of six, playing one of the 24 Caprices of Paganini in her native Osaka. In 1982 she and her mother moved to New York City, where Midori started violin studies with Dorothy DeLay at the Pre-College Division of Juilliard School and the Aspen Music Festival and School. As her audition piece, Midori performed Bach's thirteen-minute-long Chaconne, generally considered one of the most difficult solo violin pieces. In the same year, she made her concert debut with the New York Philharmonic under Zubin Mehta, a conductor with whom she would later record on the Sony Classical label.

In 1986 came her legendary performance of Leonard Bernstein's Serenade at Tanglewood, conducted by Bernstein [shown together in the photo at right]. During the performance, she broke the E string on her violin, then again on the concertmaster's Stradivarius after she borrowed it. She finished the performance with the associate concertmaster's Guadagnini and received a standing ovation. The next day's The New York Times front page carried the headline, "Girl, 14, Conquers Tanglewood with 3 Violins".

When Midori was 15, she left Juilliard Pre-College after four years and became a full-time professional violinist. In October 1989, she celebrated her 18th birthday with her Carnegie Hall orchestral debut, playing Bartok's Violin Concerto No. 2. She made her Carnegie Hall recital debut in 1990 four days before her 19th birthday. Both performances were critically acclaimed. In 1990, she also graduated from the Professional Children's School which she attended for academic subjects.

In 1992, she formed Midori and Friends, a non-profit organization that aims to bring music education to children in New York City and in Japan after learning of severe cutbacks to music education in U.S. schools. Her organization Music Sharing began as the Tokyo branch-office of Midori and Friends, and was certified as an independent organization in 2002. Music Sharing focuses on education about Western classical music and traditional Japanese music for young people, including instrument instruction for the disabled. Its International Community Engagement Program is a training program for internationally chosen aspiring musicians that promotes cultural exchange and community engagement.

In 2000, Midori graduated magna cum laude from the Gallatin School at New York University with a bachelor's degree in Psychology and Gender Studies, completing the degree in five years while also continuing to perform in concerts. She later earned a master's degree in psychology from NYU in 2005. Her master's thesis was about pain research. In 2001, Midori had returned to the stage and took a teaching position at the Manhattan School of Music. Also in 2001, with the money Midori received from winning the Avery Fisher Prize, she established the Partners in Performance program focusing on classical music organizations in smaller communities. In 2004, Midori launched the Orchestra Residencies program in the U.S. for youth orchestras, which was expanded to include collaborations with orchestras outside the U.S. in 2010.

In 2004, Midori was named a professor at University of Southern California's Thornton School of Music where she is holder of the Jascha Heifetz Chair. She became a full-time resident of Los Angeles in 2006 after a period of bicoastal commuting, and was promoted to the chair of the Strings Department in 2007. In 2012 she was named distinguished professor at USC, elected to the American Academy of Arts & Sciences, and was awarded an honorary doctorate in music by Yale University. Midori was Humanitas Visiting Professor in Classical Music and Music Education at Oxford University 2013–2014. She joined the violin faculty of Philadelphia's Curtis Institute in the 2018–2019 academic year while remaining on the University of Southern California Thornton School of Music's violin faculty as a Judge Widney Professor of Music.
