Richard Hely Hely-Hutchinson, 1st Earl of Donoughmore (29 January 1756 – 22 August 1825), styled The Honourable Richard Hely-Hutchinson from 1783 to 1788, was an Irish peer and politician.
He commissioned the building c.1790 of the Georgian style Knocklofty House near Clonmel in County Tipperary. He was created Viscount Donoughmore, of Knocklofty, Co. Tipperary (Peerage of Ireland), on 20 November 1797, with a special remainder to his mother's male descendants and, in 1800, Earl of Donoughmore. He was one of the original 28 Irish Representative peers and an advocate of Roman Catholic emancipation. He was created, in 1821, Viscount Hutchinson (in the Peerage of the United Kingdom) and thus gained an hereditary seat in the House of Lords.[citation needed]
