Richard Temple-Nugent-Brydges-Chandos-Grenville, 1st Duke of Buckingham and Chandos (1776-1839), was the son and successor of George Nugent-Temple-Grenville, 1st Marquess of Buckingham and the grandson of prime minister George Grenville.

He was created Duke of Buckingham and Chandos in 1822, his wife being only daughter of the 3rd Duke of Chandos; he was in the same patent created Earl Temple of Stowe, with special remainder as regards this title, in virtue of which, on the death without male issue in 1889 of the 3rd Duke of Buckingham and Chandos and the consequent extinction of the original earldom of Temple, the title of Earl Temple of Stowe devolved upon William Stephen Gore-Langton (1847-1902), whose mother was granddaughter of the 1st duke of Buckingham, grantee of this earldom. In 1902 Algernon William Stephen Temple-Gore-Langton (b. 1871) became 5th Earl Temple.
