James S. Bolger (born 25 December 1941) is a thoroughbred racehorse trainer and breeder based in Coolcullen in County Kilkenny.
Aidan O'Brien, Tony McCoy and Paul Carberry were all apprenticed to him before gaining professional recognition in their own right.
Talk of an English Triple Crown bid was imminent, but Teofilo suffered a career-ending injury in the lead up to the 2,000 Guineas and never saw a racecourse again.
A week later, Bolger revealed that his horse would go to Epsom after all, which led to much criticism from punters and bookmakers alike.
However, New Approach won the English Derby by a half length, beating the Sir Michael Stoute-trained Tartan Bearer.
