The RTÉ Philharmonic Choir has been at the centre of choral music in Ireland since its foundation by Colin Mawby in 1985 following the introduction of new choral policy. The choir was further developed by Mark Duley, Chorus Master for 15 years (1996-2011), and has become the country's premier symphonic choral ensemble , performing more than 56 major choral works since its foundation, mostly in conjunction with the RTÉ orchestras. The choir also broadcasts frequently on RTÉ lyric fm.

The choir members, all of whom commit their services entirely voluntarily, meet each Wednesday from 7.30pm-10.00pm for rehearsals in the Donnybrook area. Occasional weekend workshops focus on an upcoming programme and give the opportunity to work more intensively on technique and musicianship. The Phil has always been keen to emphasise the enjoyment of music-making as well as the hard work and committment required , it's members coming from Dublin and surrounding counties and spanning all generations!

The RTÉ Philharmonic Choir will be an integral part of the 2011/12 RTÉ National Symphony Orchestra Season performing Orff, Bach, Mozart and Brahms, all in original languages, with renouned international conductors Alan Buribayev, Gerhard Markson, Matthew Halls and Paul McCreesh. Their two guest Chorus Masters for this Season will be Jeremy Haneman (Orff, Brahms) and Mark Hindley (Bach, Mozart).
