Henry Pelham (25 September 1694 – 6 March 1754) was a British Whig statesman, who served as Prime Minister of Great Britain from 27 August 1743 until his death. He was the younger brother of Thomas Pelham-Holles, 1st Duke of Newcastle, who served in Pelham's government and succeeded him as Prime Minister. Pelham is generally considered to have been Britain's third Prime Minister after Sir Robert Walpole and the Earl of Wilmington.
Pelham's premiership was relatively uneventful in terms of domestic affairs, although it was during his premiership that Great Britain experienced the tumult of the 1745 Jacobite uprising. In foreign affairs, Great Britain fought in several wars. Upon Pelham's death, his brother Newcastle took full control of the ministry.
