James Sproule Myles (1877 – 13 February 1956) was an Irish soldier, politician and rugby union player.
Myles played rugby for City of Derry and Ireland. In October 1899, together with Thomas Harvey, he was a member of the Ireland team that went on a tour of Canada. This was their first ever overseas tour. While playing, he broke his leg and he had to remain in Canada until December while the rest of the touring party returned home in November.
Myles served as an independent Teachta Dála (TD) in Dáil Éireann for twenty years. He was elected on his first attempt at the 1923 general election and was subsequently re-elected six times, winning the greatest number of first preferences in each of the seven elections. He initially represented Donegal but then switched to Donegal East when the 8-seat constituency was divided in 1937.
