William John Jones (4 February 1894 â 15 July 1978) was a Welsh international rugby union player.
Jones was born in Cefneithin and attended Carmarthen Grammar School.
A forward, Jones played for Llanelly and was capped for Wales against Ireland at Cardiff in the 1924 Five Nations. He was invited to be a reserve for their next fixture in Paris, but had to make himself unavailable owing to the illness of his wife.
Jones was working as a school teacher in the village of Cross Hands at the time of his Wales cap. He was later the primary school headmaster of future Wales cap Carwyn James.
