Saint Thomas Church, located at the corner of 53rd Street and Fifth Avenue in the borough of Manhattan, New York, New York in the United States, is an Episcopal parish church of the Episcopal Diocese of New York. It is also known as Saint Thomas Church Fifth Avenue or as Saint Thomas Church in the City of New York and was incorporated on 9 January 1824. The current structure, completed in 1914, is the fourth church built to house this congregation and was designed by the architects Ralph Adams Cram and Bertram Grosvenor Goodhue in the French High Gothic Revival style.

The church is home to the Saint Thomas Choir of Men and Boys a choral ensemble comprising men and boys which performs music of the Anglican tradition at worship services and offers a full concert series during the course of the year. The boys of the Saint Thomas Choir (as the men are professional singers) are enrolled at the Saint Thomas Choir School, the only church-affiliated residential choir school in the United States.
