Richard Plantagenet Campbell Temple-Nugent-Brydges-Chandos-Grenville, 3rd Duke of Buckingham and Chandos (10 September 1823 – 26 March 1889), styled Earl Temple until 1839 and Marquess of Chandos from 1839 to 1861, was a British soldier and politician of the 19th century. He was a close friend and political ally of Benjamin Disraeli and served as Secretary of State for the Colonies from 1867 to 1868 and Governor of Madras from 1875 to 1880. As Governor, he handled the relief measures for the victims of the Great Famine of 1876-78. Buckingham also served as Lord of the Treasury, Keeper of the Privy Seal of the Prince of Wales, Deputy Lieutenant of Buckinghamshire, Chairman of the London and North-Western Railway, member of the Imperial Privy Council, Lord President of the Council and chairman of the committees in the House of Lords. In 1868, he established his right to the title of Lord Kinloss in the Peerage of Scotland, which had become dormant.
With no male issue, the dukedom of Buckingham and Chandos became extinct, but the 3rd Duke's eldest daughter, Lady Mary, succeeded him in the Scottish lordship of Kinloss.  Mary Morgan-Grenville, 11th Lady Kinloss (1852–1944) was made a Companion of the Order of the Crown of India in 1878.
