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. The choir has taken various forms since its foundation, and has existed in its present form since 1982 when, shortly after the admission of girls to the University of Cambridge, 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 also 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.

The choir typically numbers between 25 and 35 members, most of whom are taken from within Trinity College.

In January 2011, Gramophone named the choir the fifth best choir in the world
