Jeanine Tesori (formerly known as Jeanine Levenson) is a composer of musicals. She is perhaps best known for the Broadway musical Thoroughly Modern Millie; she composed eleven new songs for the show and added them to three from the movie version; four previously written songs from the 1920s were also added to the musical's score. She also composed the music for the Broadway musical Caroline, or Change, with lyrics by Tony Kushner. She contributed music to the 1998 Broadway production of William Shakespeare's Twelfth Night.
