Brian Richard Williams (9 July 1960 - 7 February 2007) was a Welsh international rugby union player.
Williams was born in Penffordd, near Maenclochog in Pembrokeshire, into the West Wales farming community.
His build may have delayed him being selected to play for Wales, and he had to wait for his international debut until 1990, by which time Neath coach Ron Waldron had taken charge of the Welsh team.
When Ospreys prop Duncan Jones led Wales for the first time in June 2006, he said that he had "always looked up to Brian Williams in the way he played.
Williams died at the age of 46 in Llangolman, in Pembrokeshire of a suspected heart attack, having been actively involved in a club reunion at The Gnoll rugby ground only four days earlier.
