Philip Yorke, 2nd Earl of Hardwicke, PC, FRS (9 March 1720 – 16 May 1790), styled Viscount Royston between 1754 and 1764, was an English politician and writer.

The eldest son of Philip Yorke, 1st Earl of Hardwicke, he was educated at Newcome's School and later Corpus Christi College, Cambridge.

During the political crisis over the loss of Minorca to the French in 1756, Lord Royston was tapped with collecting favourable press accounts of the ministry.

He joined his father, as well as Lord Mansfield, to defend the Newcastle ministry during the parliamentary inquiries following the execution of Admiral John Byng.

[5] With his brother, Charles Yorke, he was one of the chief contributors to Athenian Letters; or the Epistolary Correspondence of an agent of the King of Persia residing at Athens during the Peloponnesian War (4 vols., London, 1741), a work that for many years had a considerable vogue and went through several editions.
