Charles Philip Yorke, 5th Earl of Hardwicke, PC, DL (23 April 1836 – 18 May 1897), styled Viscount Royston until 1873, was a British aristocrat, Conservative politician and dandy.

[6] Hardwicke was returned to Parliament for Cambridgeshire in 1865[3][7] (succeeding his uncle Eliot Yorke) and served under the Earl of Derby and Benjamin Disraeli as Comptroller of the Household between 1866 and 1868.

[13][14] An inveterate gambler, the 5th Earl racked up huge debts with the Agar-Robartes Bank[citation needed] and was obliged to put the Wimpole Hall Estate up for sale by auction in 1891.

When it failed to raise the reserve price Lord Robartes, as Chairman of Agar-Robartes Bank, accepted the estate in settlement.

Lord Hardwicke married Lady Sophia Georgiana Robertina, daughter of Henry Wellesley, 1st Earl Cowley, in 1863.
