James Havard Thomas (22 December 1854 – 6 June 1921) was a Bristol-born sculptor active in London and Capri. He became the first Chair of Sculpture at the Slade School of Art in London. He was known for his painstakingly precise sculptures resulting from elaborate and time-consuming processes for achieving sculptural realism. He emerged from the same roots as the "New Sculpture" in Britain, and his career runs parallel to (and in dialogue with) that movement.
