Richard Boyle, 9th Earl of Cork

Richard Edmund St Lawrence Boyle, 9th Earl of Cork KP, PC (19 April 1829 – 22 June 1904), styled Viscount Dungarvan between 1834 and 1856, was a British courtier and Liberal politician. In a ministerial career spanning between 1866 and 1895, he served three times as Master of the Buckhounds and twice as Master of the Horse.

Boyle was born in Dublin, Ireland, the eldest son of Charles Boyle, Viscount Dungarvan, by his wife Lady Catherine St Lawrence, daughter of William St Lawrence, 2nd Earl of Howth. He was the grandson of Edmund Boyle, 8th Earl of Cork. He was educated at Eton and Christ Church, Oxford. He became known by the courtesy title Viscount Dungarvan on the early death of his father in 1834. He was a member of Brooks's and White's clubs. On 20 July 1850, he was commissioned a captain in the North Somerset Yeomanry.

Lord Dungarvan was elected Member of Parliament for Frome at a by-election in 1854, a seat he held until 1856, when he succeeded his grandfather in the earldom and entered the House of Lords. In 1860 he was made a Knight of the Order of St Patrick. He became a government member in January 1866, when he was appointed Master of the Buckhounds under Lord Russell, a post he held until the administration fell in July 1866. He was sworn of the Privy Council in May of that year. He was once again Master of the Buckhounds under William Ewart Gladstone between 1868 and 1874 and between 1880 and 1885. In 1882 he was appointed one of the speakers of the House of Lords. When Gladstone became prime minister for the third time in February 1886, Cork was appointed Master of the Horse. However, the government fell in July of the same year. He did not serve in Gladstone's fourth administration of 1892 to 1894, but when Lord Rosebery succeeded as prime minister in March 1894, Cork was once again appointed Master of the Horse. The Liberal government fell in June the following year.

Lord Cork was also Lord Lieutenant of Somerset from 1864 to 1904, an Aide-de-Camp to Queen Victoria from 1889 to 1899 and a Colonel of the North Somerset Yeomanry.
