Harry "Jersey" Flegg (6 April 1878 in Bolton, Lancashire – 23 August 1960 in North Sydney, New South Wales) was an English-Australian rugby league identity. Both a player and administrator, he was a leading figure in the birth of the sport in Australia. Flegg emigrated to Australia at an early age. He received his nickname 'Jersey' while still at school, after a meeting with the New South Wales (NSW) Governor of the time, Lord Jersey, who had bright red hair, similar to his own.
