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.

The Wales national rugby union team represents the Welsh Rugby Union in men's international rugby union. Its governing body, the Welsh Rugby Union (WRU), was established in 1881, the same year that Wales played their first international against England. The team plays its home matches at the Millennium Stadium in Cardiff, which replaced Cardiff Arms Park as the national stadium of Wales in 1999.
