The Choir of Trinity College, Cambridge is a mixed choir whose primary function is to sing choral services in the Tudor chapel of Trinity College, Cambridge. In January 2011, Gramophone named the choir the fifth best choir in the world. The choir has taken various forms since its foundation, and has existed in its present form since 1982 when, shortly after the admission of women to the college, female voices were used for the first time for the choir's top lines. Three regular services are sung per week in full University Term, and the choir sings Latin grace from the minstrels' gallery in the college's Great Hall at a number of feasts. In addition, the choir undertakes projects outside term-time such as recordings, concerts, radio broadcasts and tours.

Among the musicians associated with the choir during this time were the Tudor composers Thomas Preston, Robert White and John Hilton the elder; Robert Ramsey was organist just before the English Commonwealth; the lutenist and writer Thomas Mace was a lay clerk for around 70 years from 1635; and Thomas Attwood Walmisley was organist in the early 19th century.
