John Evan Thomas, FSA (15 January 1810 – 9 October 1873) was a Welsh sculptor, notable for many sculptures both in Wales and elsewhere in the UK, such as his portrait sculptures in London. He was especially notable for the Death of Tewdrig which was exhibited at the Great Exhibition of 1851, and for his two bronze statues of Henry de Loundres and William, Earl of Pembroke in the chamber of the House of Lords .
