John Henry Chamberlain (21 June 1831 – 22 October 1883), generally known professionally as J. H. Chamberlain, was a British nineteenth-century architect based in Birmingham. Working predominantly in the Victorian Gothic style, he was one of the earliest and foremost practical exponents of the ideas of architectural theorist John Ruskin, who selected Chamberlain as one of the trustees of his Guild of St George. Chamberlain's later work was increasingly influenced by the early Arts and Crafts movement.
