The Welsh Rugby Union is the governing body of rugby union in the country of Wales, recognised by the sport's international governing body, World Rugby.

Richard Mullock was a Welsh sporting administrator and official, who is most notable for organising the first Welsh rugby union international game and was instrumental in the creation of the Welsh Football Union, which became the Welsh Rugby Union in 1934. Mullock came from an Anglo-Irish family; his family's firm in Wales, Henry Mullock & Son, was a printers based on Commercial Street in Newport, South Wales.
