Charles Watson-Wentworth, 2nd Marquess of Rockingham, (13 May 1730 – 1 July 1782; styled The Hon. Charles Watson-Wentworth before 1733, Viscount Higham between 1733 and 1746, Earl of Malton between 1746 and 1750 and The Marquess of Rockingham in 1750) was a British Whig statesman, most notable for his two terms as Prime Minister of Great Britain. He became the patron of many Whigs, known as the Rockingham Whigs, and served as a leading Whig grandee. He served in only two high offices during his lifetime (Prime Minister and Leader of the House of Lords), but was nonetheless very influential during his one and a half years of service.
