Saint Thomas Choir School is a church-affiliated boarding choir school in Manhattan, New York, founded in 1919. The school is supported by the nearby Saint Thomas Church, an Episcopal church, continuing the Anglican tradition of all-male choral ensembles. Saint Thomas is one of three choir schools that exclusively educate boy trebles of the choir, and where all boys are required to board at the school (Westminster Abbey Choir School in England and Escolania de Montserrat in Spain being the other two).
