Moore Hall, or Moorehall, the house and estate of George Henry Moore and family, is situated to the south of the village Carnacon in the barony of Carra, County Mayo in a karst limestone landscape.

George Henry Moore was an Irish politician who, in the 1850s, was a co-founder 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. He was the father of the novelist George Augustus Moore and of the Fianna Fáil Senator Maurice George Moore.
