Arthur Richard Wellesley, 2nd Duke of Wellington (3 February 1807 - 13 August 1884) was the son and successor to Arthur Wellesley, 1st Duke of Wellington. He succeeded his father in 1852 and was made a Privy Councillor in 1853 and a Knight of the Garter in 1858. In 1863 he inherited the Irish title of Earl of Mornington from his cousin. In 1839 he had married Lady Elizabeth Hay, but they had no children, so at his death he was succeeded in his titles by his nephew, Henry.
