William Joseph Jenkins (18 May 1885 - 23 December 1956) was a Welsh international forward who played club rugby for Canton RFC and Cardiff.
His younger brother Eddie became a football player of note in the association game winning a single cap for Wales in 1925.
[2] Jenkins joined Cardiff in the 1909–10 season, but it wasn't until 1912 that he was selected to play for Wales.
Two weeks later he played his second game for Wales, this time at Rodney Parade against France.
Jenkins was one of the seven players to survive this cull and he was chosen to play in two matches the next season in the 1913 Five Nations Championship.
