Percy Jones (26 December 1892 – 25 December 1922) was a Welsh professional boxer who competed from 1911 to 1916. He became the first Welshman to win a World championship when he took the IBU flyweight title from Bill Ladbury in 1914. The IBU later became the EBU and that is why the achievement was taken into context when comparing fighters of the same era. Jones also took the British and European flyweight titles from Ladbury in the same match. He has been voted number 6 in a BBC poll of Welsh boxing greats.
