John Miller (1931–2002) was an English artist born in London who became famous for his idyllic representation of beach scenes in his home county of Cornwall. Most of his paintings were of the West Penwith peninsula and Tresco in the Isles of Scilly.
During the 1970s John Miller emerged as a cultural figurehead within Cornwall. He became well known as a painter of popular, Monet-like Cornish scenes (many of which were cheaply reproduced as prints for the tourist trade), as an art teacher, a television personality, a patron of local charities and an active supporter of the Church of England. He was also responsible for some high profile architectural projects including a reordering of the interior of Newlyn Art Gallery.
