John Thomas Doyle (29 May 1915 — 3 October 1998) was an Irish international rugby union player.
Born in Rathdown, County Dublin, Doyle played his rugby for Bray and was capped once for Ireland as a wing three-quarter against Wales at Belfast. He contributed a try in an Ireland win, but didn't get any further opportunities. Other than rugby, Doyle was also a sprinter and competed in equestrian events.
Doyle became a successful bloodstock agent. He most famously selected the long-shot 1963 Cheltenham Gold Cup-winning horse Mill House for Bill Gollings.
