Henry Fitzalan-Howard, 15th Duke of Norfolk,, styled Lord Maltravers until 1856 and Earl of Arundel and Surrey between 1856 and 1860, was a British Unionist politician and philanthropist. He served as Postmaster General between 1895 and 1900, but is best remembered for his philanthropic work, which concentrated on Roman Catholic causes and the city of Sheffield.

Postmaster General of the United Kingdom was a Cabinet ministerial position in HM Government. Aside from maintaining the postal system, the Telegraph Act 1868 established the Postmaster General's right to exclusively maintain electric telegraphs. This would subsequently extend to telecommunications and broadcasting.
