Sir William Henry Gregory PC (Ire) (12 July 1817 - 6 March 1892) was an Anglo-Irish writer and politician. The only child of Robert Gregory and Elizabeth O'Hara Gregory, he was born at the Castle, in Dublin's Phoenix Park. From 1830 to 1835 he attended Harrow, where he was an award-winning student. He subsequently entered Christ Church, Oxford in 1836 but left three years later without receiving a qualification. Gregory was elected to the British House of Commons in an 1842 by-election as a Conservative member for Dublin. Among his close associates were Sir Robert Peel, Lord Lincoln, and Lord George Bentinck. After Gregory failed to retain his seat in the 1847 general election, he took up residence at the family estate at Coole Park in County Galway. He was appointed High Sheriff of County Galway in 1849.
