Ruabon Druids F.C. were a football club based in village of Ruabon near Wrexham, Wales. The club was founded in 1869 as Plasmadoc F.C. by David Thomson and his brother, George, of Ruabon. In 1872, Plasmadoc amalgamated with two other Ruabon clubs, Ruabon Rovers F.C. and Ruabon Volenteers F.C., and under the guidance of Llewelyn Kenrick became Ruabon Druids.
