|Rugby union career|
Nathan Rocyn-Jones FRCS (17 July 1902 - 26 January 1984) was a Welsh international rugby union forward who played club rugby for Newport Rugby Football Club and represented Cambridge. He won only a single cap for Wales but after retiring from playing rugby became President of the Welsh Rugby Union.
Rocyn-Jones came from a long-line of medical practitioners and his father, Sir David Rocyn-Jones was Medical Officer for Health for Monmouthshire. While studying medicine at Cambridge, Rocyn-Jones represented the University, but it was while at St Mary's Hospital, London, would gain his one and only cap for Wales, when he was selected to face Ireland as part of the 1925 Five Nations Championship. The game took place at Ravenhill, Belfast, and Wales were led by Llanelli's Idris Jones. Wales were outclassed and lost 19-3.
Although Rocyn-Jones did not play for Wales again, he served the club later in his career, when, like his father before him, he was made President of the Welsh Rugby Union. His presidency lasted only a year, but his time coincided with the 1964-65 Triple Crown winning team. During his presidency, Rocyn-Jones clashed with the Welsh selectors, which included past Welsh players like Cliff Jones, Harry Bowcott and Rees Stephens, over the nature of the Welsh play. Rocyn-Jones believed that the game was "essentially played for enjoyment and that too much emphasis could be placed on technical and tactical skill" .
