Henry Pelham Archibald Douglas Pelham-Clinton, 7th Duke of Newcastle-under-Lyne (28 September 1864 – 30 May 1928), was an English nobleman, styled Earl of Lincoln until 1879.
He held a number of local offices appropriate to his rank and station, such as High Steward of Retford, Master Forester of Dartmoor and Keeper of St Briavel's Castle.
In 1879 a serious fire destroyed much of Clumber House; he had it magnificently rebuilt to designs by the younger Charles Barry.
The Duke was actively involved in the rebuilding process, and in particular in the design and building of the magnificent St Mary the Virgin Chapel in the grounds.
Some of the 7th Duke's personal papers are now held at Manuscripts and Special Collections, The University of Nottingham.
