Owen Rhys Williams (born 27 January 1986) is a Welsh former rugby union player who played as a wing.
Williams began playing for Blackwood in the club's junior division at the age of 11.
In February 2008, Pontypridd RFC visited Blackwood's Glan-yr-Afon Park for a Konica Minolta Cup match, in which Williams impressed enough for the Premiership side to sign him on permit for the rest of the 2007–08 season; Williams' season culminated with him starting for Pontypridd in the Konica Minolta Cup Final against Neath.
In December that year, he was called up to the senior Wales Sevens team for the 2011 South Africa Sevens, helping the team to win the Plate after being eliminated from the Cup in the quarter-finals.
