Wye Jamison "Wendy" Allanbrook (March 15, 1943 – July 15, 2010) was an American musicologist whose writings demonstrated that much of the music of Mozart and his contemporaries was influenced by the social dances of the time.

She earned a Ph.D. from Stanford University in 1974, where her doctoral dissertation became the basis for her 1983 book Rhythmic Gesture in Mozart: 'Le Nozze di Figaro' and 'Don Giovanni' published by the University of Chicago Press, in which she demonstrated that Mozart's music integrated references to the social practices and dances of his period.

[2] Her research influenced the way in which directors and conductors, including Roger Norrington and Peter Sellars, have staged Mozart's operas.

Her book The Secular Commedia: Comic Mimesis in Late Eighteenth-Century Music was completed by her colleagues Mary Ann Smart and Richard Taruskin based on the content of her "Bloch lectures," delivered in fall 1994 at UC Berkeley, and was published in 2014 by the University of California Press.

[1] Her marriage to Douglas Allanbrook, a musician and composer who was a longtime professor at St. John's College, ended in divorce.
