Daniel O'Brien, 3rd Viscount Clare (died 1691), was with King Charles II in exile during the interregnum. At the Restoration, he obtained the title of Viscount Clare for his grandfather and full restoration of the family's lands. At the Glorious Revolution he supported James II, sitting in the Patriot Parliament and fighting for him at the Battle of the Boyne. He was in consequence attainted as a Jacobite.
