Rees Thomas (1882–14 June 1926) was a Welsh international rugby union back row player who was utilised usually as a flanker or Number 8.
The first was a loss to England at Twickenham, followed by a more convincing display and a win at St Helen's over Scotland.
At the end of 1912, Thomas was selected to represent Monmouthshire against the touring South African team.
Thomas was one of three capped players in the Monmouthshire team, the others were Newport's Reg Plummer and Abertillery's Jim Webb.
