George Henry Moore (1 March 1810 – 19 April 1870) was an Irish politician, co-founder in the 1850s of the Tenant Right League, of the Catholic Defence Association and, as the Member for Mayo in the United Kingdom Parliament, of the Independent Irish Party. Although an advocate of tenant rights, and renowned for his relief efforts during the Great Famine, at the time of his death in 1870 Moore was defending his rights as a landowner against an oath-bound tenant society, the Ribbonmen. Family George Henry Moore was born 1 March 1810 in Moore Hall, Ballyglass, Co. Mayo, the eldest of three sons born to Louisa Moore (née Browne), granddaughter of John Browne, 1st Earl of Altamont and George Moore (1770–1840), landowner and historian, the son of a wealthy merchant.

From 1834 he traveled abroad, visiting Russia, Syria, and Palestine. On his father's death in 1840 he was recalled again to Mayo where he established a successful racing stable. After his brother Augustus was killed riding at Aintree in the 1845 English Grand National, and before selling his horses, Moore made one last grand wager. He won £10,000 on his own horse in the 1846 Chester Cup. The winnings he was to deploy, in part, for Irish famine relief. Organiser of Famine relief During the Great Famine (1845-1852) Mayo was one of the counties worst ravaged by starvation and illness, but none of Moore's tenants starved, nor were any evicted—a fact he was to uphold twice in libel cases against The Times regarding the treatment of
