Hugh Charles Clifford, 7th Baron Clifford of Chudleigh (29 May 1790 – 28 February 1858) was a British peer. He inherited the title from his father on 29 April 1831.
Clifford, eldest son of Charles Clifford, 6th Baron Clifford of Chudleigh, and Eleanor Mary Arundell, daughter of Henry Arundell, 8th Baron Arundell of Wardour, was born in 1790. He was educated at the Roman Catholic college of Stonyhurst, and in 1814 attended Cardinal Consalvi to the Congress of Vienna. He served as a volunteer through a large portion of the Peninsular campaigns. On succeeding to his father's estates in 1831 he took his seat in the House of Lords. He gave his general support to the ministry of Lord Grey and afterwards of Lord Melbourne, but seldom took part in the debates except on questions connected with Roman Catholicism. In his later years he lived chiefly in Italy, where he had a house near Tivoli. He died at Rome on 28 February 1858 from an injury.
By his wife, Mary Lucy, the only daughter of Thomas (afterwards Cardinal) Weld (died 1837) of Lulworth Castle, Dorsetshire, and his wife, Lucy (née Clifford; died 1815), he left two daughters and four sons. Their eldest son, Charles Hugh, became the 8th Baron Clifford.
Clifford was the author of a Letter to Edmund Burke on the Repeal of the Corn Laws (1824); Letters addressed to Lord Alvanley on his pamphlet, "The State of Ireland considered" (1841) and Letters to the Editor of the Morning Chronicle on the East Indian Question, as well as several published speeches.
