Walter Field (1 December 1837- 23 December 1901) was an English painter.
He was the youngest son of Edwin Wilkins Field by his second wife, Letitia Kinder, and was born at Windmill Hill, Hampstead, on 1 December 1837. He was a lineal descendant of Oliver Cromwell. After education at University College School, London, he was taught painting by John Rogers Herbert and John Pye the engraver gave him lessons in chiaroscuro. Making art his profession, he painted outdoor figure subjects and landscapes, especially views of Thames scenery, which were often enlivened with well- drawn figures; he also produced a few portraits. At first he worked chiefly in oil, but subsequently executed many drawings in water-colour. His landscapes and coast scenes show skilful technique.
Between 1856 and 1901 he exhibited at the Old Water Colour Society (Royal Society of Painters in Water Colours), at the Royal Academy (where he showed forty-two pictures), the British Institution (where he showed nine pictures), the Royal Society of British Artists, Dudley Gallery, and elsewhere. He was elected an associate of the Old Water Colour Society on 22 March 1880, but never attained full membership. He was also one of the earliest members of the Dudley Gallery, whose first exhibition was held in 1865.
Field resided principally at Hampstead, and was untiring in his efforts for the preservation of the natural beauties of Hampstead Heath; he was the main founder of the Hampstead Heath Protection Society. By his wife, Mary Jane Cookson, whom he married on 14 May 1868, he had seven children. They included Edwin Field, known as a rugby player.
Field died at The Pryors, East Heath Road, on 23 December 1901, and was buried in Hampstead Cemetery.
