David Griffiths (born February 16, 1939 in Liverpool, United Kingdom) is a Welsh portrait painter. The family moved to Pwllheli when Griffiths was seven. He studied at the Slade School of Fine Art, London under the direction of Professor Sir William Coldstream.
Regarded as one of the U.K's foremost portrait painters, David Griffiths' large output of work include portraits of royalty, ambassadors, archbishops, Lords Chancellor, distinguished parliamentarians, and well-known musicians and actors. It was his portrait of Prince Charles on the occasion of Charles' investiture as Prince of Wales in 1969 which brought him to general notice. This remains one of his best-known portraits. He has also painted William S. Farish (ex-U.S. Ambassador to the United Kingdom), Enoch Powell, and a long list of Welsh notables including Barry John, Gwynfor Evans, John Meurig Thomas, Lord Tonypandy (as Speaker of the House of Commons), Siān Phillips, Bryn Terfel and Sir Geraint Evans.
The Midland Bank sponsored a major exhibition of his work at the 1970 National Eisteddfod. In 2002, the National Library of Wales held a retrospective show of his work.
