Tom Williams (c.1887 - 13 August 1927) was a Welsh international forward who played club rugby for Swansea.

He turned out on 9 March 1912 against Ireland at the Balmoral Showgrounds, in a match Wales lost 12–5.

Two weeks later he played his second and last game for Wales, this time at Rodney Parade against France.

Williams impressed enough to return for the next season and played against France in the 1913 Championship scoring his one and only international try during the game.

[1] The match against Ireland in 1914 is seen as one of the most notoriously violent games in international rugby union, and Williams and the rest of the Welsh pack were dubbed the 'Terrible Eight' for their rough style of play.
