Cor Visser (26 August 1903, Spaarndam, North Holland – 27 September 1982, Ipswich) was a Dutch artist who spent much of his life living in and around Suffolk in the United Kingdom. He first sailed to England in 1937 where he became particularly associated with the River Orwell, painting numerous watercolours of the river and surrounding area. During the Second World War he was appointed official war artist to the Dutch Royal Family, then living in exile in London, where he painted many culturally important portraits of members of the royal family as well as key exiled government officials and military officers. A selection of his work is exhibited in the Rijksmuseum Amsterdam, the Victoria and Albert Museum and the National Portrait Gallery in London. The Ipswich Borough Council's Museums and Galleries Collection also contains a large selection of his paintings.
