Eifion Wyn Jones (born 25 June 1942 in Velindre, Glamorgan) was a Welsh cricketer who played for Glamorgan County Cricket Club.
When he first came to Glamorgan, Jones was a specialist right-handed batsman but after being tutored by Phil Clift he became a wicketkeeper.
However, the continued good form of Alan Knott and Bob Taylor kept him out of consideration for the Test team.
In 1968, he made the highest ever score by a Glamorgan keeper with 146 not out against Sussex.
Thereafter, his batting gradually declined, and after 1975 he never averaged as high as 20 in a season.
