Henry Pelham Fiennes Pelham-Clinton, 5th Duke of Newcastle-under-Lyne, KG, PC (22 May 1811 – 18 October 1864), styled Earl of Lincoln before 1851, was a British politician and aristocrat. He sat in Parliament for South Nottinghamshire (1832–46) and for Falkirk Burghs (1846–51) until inheriting the dukedom.

Newcastle held several key offices in the mid-19th century, including Chief Secretary for Ireland, Secretary of State for the Colonies, and Secretary of State for War and the Colonies. In 1855, he resigned as Secretary of State for War owing to disastrous casualties during the Crimean War (1853–56).
