Treorchy Male Voice Choir is a choir based in Treorchy in the Rhondda Valley, Wales, United Kingdom. Choirs have existed in the Rhondda Valley for more than a hundred and fifty years and Treorchy is one of the best known from the area. One of its first male choirs was formed in the Red Cow Hotel in the summer of 1883 and developed into a National Eisteddfod winner, culminating in a royal command performance for Queen Victoria at Windsor Castle in 1895. The choir would later disband after the South Wales Valleys suffered during the massive economic downturn of the Great Depression in the United Kingdom and two World Wars, but they would later reform into a male voice choir that gained international recognition.
