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.
