Cowper was the eldest son of Peter Clavering-Cowper, 5th Earl Cowper, and his wife Emily Lamb, daughter of Peniston Lamb, 1st Viscount Melbourne, sister of Prime Minister William Lamb, 2nd Viscount Melbourne, and a leading figure in Regency society. William Cowper-Temple, 1st Baron Mount Temple, was his younger brother. His mother married as her second husband the future Prime Minister Henry Temple, 3rd Viscount Palmerston, in 1839.

He was commissioned a cornet in the Royal Horse Guards on 28 April 1827. On 27 February 1830, he purchased a lieutenancy in the regiment.

He retired from the army on 6 March 1835.

Cowper entered the House of Commons for Canterbury in the 1830 general election, and served briefly under his uncle Lord Melbourne as Under-Secretary of State for Foreign Affairs between November and December 1834. He lost his seat in Parliament in the 1835 general election. Two years later he succeeded his father in the earldom. Between 1846 and 1856 he served as Lord-Lieutenant of Kent.

Lord Cowper married Lady Anne Florence de Grey (who after her husband's death succeeded as sixth Baroness Lucas of Crudwell), daughter of Thomas de Grey, 2nd Earl de Grey, in 1833.
