John Clayton (10 June 1792 – 14 July 1890) was an antiquarian and town clerk of Newcastle upon Tyne, England, during the nineteenth century. He worked with the builder Richard Grainger and architect John Dobson to redevelop the centre of the city in a neoclassical style (Grainger Town), and Clayton Street in Newcastle is named after him. He did much to preserve the remains of Hadrian's Wall. Early life and career Son of Nathaniel Clayton (Town Clerk of Newcastle upon Tyne from 1785 to 1822), he was educated at Kirkoswald School in Northumberland and received classical education at Uppingham.
