The Ambrosian Singers are one of the best-known London choral groups, particularly appreciated for its great variety of recorded repertory.

They were founded after World War II in England. One of their co-founders was Denis Stevens (1922–2004), a British musicologist and viola player who joined the BBC Music Department in 1949 and developed programs of Renaissance and early Baroque music. The other was John McCarthy (1919–2009), a professional tenor soloist.
