Penry Williams (1802 – 27 July 1885) was a Welsh artist who spent most of his life in Rome.
Sent to London by Sir John Guest and others, he studied in the schools of the Royal Academy under Henry Fuseli, and in 1821 gained a silver medal from the Society of Arts for a "drawing from the antique".
[3] In April 1828 Williams was elected an associate of the Society of Painters in Watercolours, exhibiting annually until 1833, when he resigned.
Williams's Rome studio was one of the recognised attractions for English visitors, for half a century.
Among his prominent works were The Festa of the Madonna dell' Arco, Ferry on the River Ninfa, Il Voto, or the Convalescent, The Fountain: a Scene at Mola di Gaeta, Italian Girls preparing for a Festa (engraved by D. Lucas, 1830), and Procession to the Christening (engraved by Lumb Stocks for William Finden's British Gallery of Art).
